A conducting loop of finite resistance lies on the $\displaystyle x-y$ plane. There is a constant magnetic field in the $\displaystyle z$ direction. The area of the loop varies with time $\displaystyle t$, as $\displaystyle \mathrm{A}=\mathrm{A}_0(1+\sin t)$ in appropriate units. The figure that correctly indicates the qualitative behaviour of the power $\displaystyle P$ dissipated in the loop as a function of time is :
