D Correct answer
Explanation

Relative speed = 60 - 40 = 20 km/hr. Time = Distance / Relative Speed = 80 km / 20 km/hr = 4 hours.

AI explanation

The relative speed of the policeman compared to the thief is 60 km/hr minus 40 km/hr, which equals 20 km/hr. To cover the initial distance of 80 km at this relative speed, the time required is 80 km divided by 20 km/hr, resulting in 4 hours. The policeman catches the thief in 4 hours.
