I got this question in an international level competition.

My question comes from Motion in a Plane in chapter Laws of Motion of Engineering Physics I

Answer 1

Right answer is (c) Both A and B will reach the ground simultaneously

The best I can explain: Both A and B will reach the ground simultaneously. Both have zero initial velocity and cover the same height under the acceleration due to gravity.
