Solution

The correct option is C Constant
According to the law of conservation of energy, the total energy of a system is conserved. In case of free fall, if the air resistance is neglected then the body possesses both kinetic and potential energy, which is conserved throughout the motion. In other words, the sum of P.E and K.E will remain constant.
