Two Bodies Are Falling with Negligible Air Resistance, Side by Side

Two bodies are falling with negligible air resistance, side by side, above a horizontal plane.If one of the bodies is given an additional horizontal acceleration during its descent, it:

A) strikes the plane at the same time as the other body
B) strike the plane earlier than the other body
C) has the vertical component of its velocity altered
D) has the vertical component of its acceleration altered
E) follows a straight line path along the resultant acceleration vector
