Newton's Laws - Mission NL10 Detailed Help

The diagrams below show free-body diagrams and velocity values at an instant during the fall of several objects. Based on the diagrams, which objects could be in free fall? ...

Definition of Free Fall:
Free fall is the state of an object in which the only force acting upon it is the force of gravity.

The definition of free fall (above) must be applied to this question in order to answer it successfully. If the only force is gravity, then the object is in free fall.
