5I Think that there is right answer given and the right explaination given. As I am a student , ( Kendriya Vidyalaya ) a very very very very great mistake is there in the question image. It is written 75 degree but there should be just tea written there. If you say that the image is right, no problem but the answer should be AAAAA.Do you like the solution? this is written with the supervision and direction of my science teacher.

The answer of this question should be A as the temperature is specified and same in all the glasses.
