Physics

a skydiver is subject to two forces: gravity and air resistance. Falling vertically, she reaches a constant terminal speed at some time after jumping from the plane. Since she is moving at a constant velocity from that time until her chute opens, we conclude from the work kinetic energy theorem that, over that time interval,

A. The work done by gravity equals the negative of the work done by the air resistance.
B. The work done by gravity is zero.
C. The work done by gravity equals the work done by air resistance.
D. The work done by air resistance is 0.
E. Her kinetic energy increases.

Please help me with this...
