(b) decreases
(c) remains constant
(d) first increases and then decreases

Answer: [C]

Solution.
 

The total energy of any body is the sum of kinetic energy and potential energy.
TE =KE + PE
When a body falls freely towards the earth; kinetic energy of the body increases and potential energy of the body decreases.
However, by the law of conservation of energy total energy of the body remain constant.
The correct answer to this question is option C.
