Solution

The correct option is A
1m/s

Relative Speed: It is defined as the speed of a moving object with respect to another. When two objects are moving in the same direction, relative speed is calculated as their difference. When the two objects are moving in opposite directions, relative speed is computed by adding the two speeds.

So, here Tom is chasing Jerry, so, they are running in the same direction. And hence, the relative speed will be 3m/s - 2m/s, which is equal to 1m/s.
