D: All objects fall at the same rate of acceleration regardless of their individual mass.
Explanation:
According to Newton's law of motion the resultant force and the rate of change in linear momentum are directly proportional.
Mass is inversely proportional to acceleration and directly proportional to the resultant force.
An object with more mass will have less acceleration while a lighter object will have greater acceleration.
During free fall object will fall at the same rate of acceleration regardless of their individual mass.
Object under free fall are influenced by gravity and air resistance which is negligible and thus they will have an acceleration equivalent to gravitational acceleration.
