A conducting circular loop of radius a and resistance R is kept on a horizontal plane. A vertical time varying magnetic field B =2t is switched on at time t = 0. Then

A)  Flow of charge per unit time from any section of the coil is constant

B)  Total charge passed through any section between time \[t=0\,\,\,to\,\,\,t=\,\,\,2\,\,\,is\,\,\left( \frac{4\pi {{a}^{2}}}{R} \right)\]

C)  Power generated in the coil at any time t is constant 

D)  All of these
