Solution

The correct option is D Person X feels that person Y is moving in backward direction after 5 min.
When both the buses A and B started moving at the same time, both the persons are at rest with respect to one another. But as the speed of the bus A increases by 1.5 times after 5 min, the person X starts feeling that person Y is moving in backward direction and person Y starts feeling that person X is moving in forward direction.
