D Correct answer
Explanation

Average speed = distance/time = 350 km/7 hrs = 50 km/hr. However, the question asks for average VELOCITY, which is a vector quantity requiring both magnitude and direction. Since we don't know the exact direction between Bangalore and Chennai, we cannot determine the average velocity. Also, the distance given might not be the straight-line displacement needed for velocity calculation.
