A conductor `ABCDE` has the shape shown. It lies i the `yz` plane, with `A` and `E` on the `y`-axis . When it moves with a velocity `v` in a magnetic field `B`, an emf `e` is induced between `A` and `E`
A. `e=0` if `v` is in the `y`-direction and `B` is in the `x`-direction.
B. `e=2Bav`, if `v` is in the `y`-direcrtion and `B` is in the `x`-direction
C. `e=Blamdav`, if `v` is in the`z`- direction and `b` is in the `x`-direction.
D. `e=Blamdav`,if `v` is in the `x` -direction and `B` is in the `z`- direction
