 So, psi universe next graph is like case first. Can I take the position that this arm is exactly passing through this point? Let us take this position first, number one. So, pi by 2 is 1 minus a, so a becomes 1 minus pi by 2. Do you see this arm is option which is close to this? No, it is C, D, D. No, D has R. We should have been square brackets. But if you say it is not a complete interval, then D can be an answer. This is not a complete interval. Next question number seven becomes minimum. That is minus 1. So, it becomes 1, 2, 3 by 2. How do you get the next step? So, that gives me a bit. So, the answer is none of these. This is not possible. At least I should have a problem. Questions are even put here. This is wrong. C is wrong. This is the correct segment. See, let us look at this. So, answer for this is C. Correct? 72. We will have to change it before that. Class 11 is getting discussed. Class 12 is getting discussed now. 72, if y is equal to... So, can I say...
