A circular conducting loop of radius `r_(0)` and having resistance per unit length lamba as shown in the figure is placed in a magnetic field B which is constant in space and time. The ends of the loop are crossed and pulled in opposite directions with a velocity v such that the loop always remains circular and the radius of the loop goes on decreasing then

A

Radius of the loop changes with `r = r_(0) -vt/pi`

B

The emf induced in the loop as a function of time is `e=2Bv(r_(0)-vt//pi)`

C

The current induced in the loop is `I= Bv//2pilamda`.

D

The current induced in the loop is `I= Bv//pilamda`.
