Answer Key : (b) -

(b)

If the velocities acquired due to explosions are in vertical direction,then options (c) and (d) are possible. If one of them follows parabolic path (or acquires velocity in horizontal direction), then other also has to follow parabolic path (or acquire velocity in horizontal direction to keep the momentum zero in horizontal direction). Hence, option(b) can never be possible
