The figure shows certain wire segments joined together to form a coplanar loop. The loop is placed in a perpendicular magnetic field in the direction going into the plane of the figure.
The magnitude of the field increases with time `I_(1)` and `I_(2)` are the currents in the segments ab and cd. Then,

A

`I_1 gt I_2`

B

`I_1 lt I_2`

C

`I_1` is in the direction ba and `I_2` is in the direction cd

D

`I_1` is in the direction ab and `I_2` is in the direction dc
