In the diagram shown, the wires `P_1Q_1` and `P_2Q_2` each of length `40cm` are made to slide on the rails with same speed of `5m//s`. In this region a magnetic field of `1T` exists. The electric current in `9kOmega` resistor is

A

zero if both wires slide towards left.

B

0.1 mA if both slide is opposite direction

C

0.2 mA if both wires move towards left.
