Rate of change of kinetic energy

(D) Power is defined as the rate of doing work,which is equal to the rate of change of kinetic energy $(KE)$ of the particle.$P = \frac{dW}{dt} = \frac{d(KE)}{dt}$.Since the power $(P)$ is given as a constant,the rate of change of kinetic energy,$\frac{d(KE)}{dt}$,must also be constant.Therefore,the rate of change of kinetic energy remains constant.
