The circles in the diagram represent different teaching capabilities among teachers. It is a representation of key set concepts.

1. Option 1 (v) refers to teachers who can teach Physics, Chemistry, and Mathematics because this area is common to all three circles. Hence, it`s not the correct answer.

2. Option 2 (u) refers to teachers who can teach only Physics and Mathematics and not Chemistry. There is no overlap here with the Chemistry circle (B), making it the correct answer.

3. Option 3 (s) represents teachers who can only teach Physics, not including Chemistry or Mathematics. So, it can`t be the correct answer.

4. Option 4 (t) represents teachers who can teach Chemistry and Mathematics, but not Physics. Therefore, this also can`t be the right answer.

So, in conclusion, option 2 (u) correctly represents teachers who can teach Physics and Mathematics but not Chemistry.
