Hope this helps.
Explanation:
The answer is: [D]: "force".

Note the formula: " F = ma" ; {"Force = mass * acceleration"}.

Since a straight line on a distance time graph implies uniform speed, and falling is an acceleration - a non uniform speed - I woul not expect a straight line.I would expect to get a parabola.This is based on the kinematic equation s=ut+(1/2)at^2. If something is dropped from rest, u = 0; so s = (1/2)at^2Which is, I think, the equation of a parabola.
I believe the answer is the core.
