But if you might think that Sarah fine in is the answer. But that is not the case, because where I dine is being treated. That is what acts has the moderates that is used in Graham sitting.

This is the final kind of color staying procedure where I dine treatment when the bacteria's air treated with iodine, the high dine is considered the modern, so the right answer would be I'm

Given how long we have been given four different types of days and we need to determine the future of them isn't as you die now water zoo dies. Okay, so Judah is the one which I will as a group that is the diet that contains this particular group are characteristic. They are said as as ouda is all right now. Mhm. In the given example, in the given question, the first option is mala shoot green, normally shed green. It has an intense green color and it is present. It is prepared by condensation of died time Ellen in and Ben's LD hide. Okay. However, it is not an as uday because it does not contain the ago group. Okay, now the second is congregated. Okay, so the congo red, it is a type of an as uday because it has the ASU group. Uh huh. Has the structure often of this. And just to me draw the structure it looks like. No. Mhm. So this is the structure of congo red dye. So if we can clearly see here there is a is a group present in this diet is an example of azo dye. Okay. And the which one? The marshes? Yellow is a yellow color organic compound which has a very poor light Fastness and is in the group indigo is an example of a natural day. It is extracted from the plants and has a characteristic color. Now in all this, the correct option here would be option B. That is Congaree

Given question we have been asked at which to type of day is mouth filling. So not to answer this question, we need to first determine the structure off and also intelligence quickly draw the structure of final Colleen. Okay. Yeah. Oh, when we well here it is the structure of finals to lean so cannot Colin. It is basically used as an indicator in as it based it operations. So what happens? It turns the color, it turns colorless in athletic solution. And I think in the basic solution. So what we have the option, the four options we have is uh calendar is a calendar either class of days, mainly whose rest ph indicators. Okay, because they have the ability to change colors depending on the ph of the solution. So this description matches the description of you know, Colin, which means that you're not clean. Even example of calendar is the other options we have our nitro to is nitro days are those days which uh, which contained the aromatic compounds, those color results and the presence of and or to group. Now there is no an auto group in the north Koreans, option B is incorrect, no driving. I'll be pain no. Are those days whose structure is built on the structure of DR final meeting. So this is also incorrect because you north Helen does not have this structure similarly as you guys are. Those in which as a group is present. That is as a group is uh and so the diets containing this particular group are classified as a soviet. The correct option is option

We have been having that with which of the what color do we get when as a Lutheran die? The outside chromium irons on CIA treatments. Irons. So we are given four options but before their lives get a little bit idea about what is eliciting Eliza ring basically. It is a type of modern die and what it does. It it gives colors by, you know, forming a coordination complex. But that is when it comes in contact with different fabrics, it forms coordination complexes that have that have specific colors. All right, so with different middle lands that give different colors. So, violet color or the first option says violet color. We obtain boil it color when else are in it reacts with magnesium irons. All right, two mg two plus. It gives Uh huh. This violet color and brown bread, brown bread it gave its er three plus three irons pink color. It gives me l Neemia minds and dread color. It will it gives with astonishing irons. Right, so here, the correct option is option B. That is with chromium and it gives ground red color
