Induced current `=1/150 A` directed clockwise if `10 Omega` resistor is pulled to the right with speed 0.5 ms and `5 Omega` resistor is held fixed

B

Induced current `=1/300 A` directed anti-clockwise if `10 Omega` resistor is pulled to the right with speed `0.5 ms^( –1)` and `5 Omega` resistor is held fixed

C

Induced current `=1/300 A` directed clockwise if `5 Omega` resistor is pulled to the left at `0.5 ms^(-1)` and `10 Omega` resistor is held at rest

D

Induced current `=1/150 A` directed anti-clockwise if `5 Omega` resistor is pulled to the left at `0.5 ms^(-1)` and `10 Omega` resistor is held at rest
