A - force responsible for the acceleration
B - Not unless there is no air otherwise there will be a viscous (frictional) drag (force) in the opposite direction to the motion of the acorn.
C - Correct unless there is no air.
D - The frictional drag is in the opposite direction to the gravitational force so the net downward force is smaller than the gravitational force.
