The selected answer is wrong:
If the train were moving with uniform velocity, the
coin would fall back to the passenger’s hand (This
is due to the inertia of motion of the coin. When it
was thrown ‘vertically’ up, it had the same
horizontal velocity as that of the train. Therefore, it
will move alongwith the train and fall back to the thrower’s hand) If the train is accelerated, the horizontal velocity of
the train would be more than that of the coin (which
remains constant through out its flight) by the time
the coin returns. Therefore, the train travels a
greater horizontal distance than the coin and the
coin falls behind the passenger.

correct answer is D uniform velocity implies no acceleration hence the coin will return back to his palms
D Is actually the correct answer since the movement is uniform the coin tossed still maintain the velocity which you through with and thereby falls Street into the palm. It's only when the vehicle accelerates or decelerate that it falls behind or in front of the palm.
