In a circuit for finding the resistance of a galvanometer by half deflection method, a 6 V battery and a high resistance of 11 `kOmega` are used. The figure of merit of the galvanometer is 60 `muA//"division"`. In the absence of shunt resistance, the galvanometer produces a deflection of `theta =9` divisions when current flows in the circuit. The value of the shunt resistance that can cause the deflection of `theta//2`, is closet to :

A

`550 Omega`

B

`220 Omega`

C

`55 Omega`

D

`110 Omega`
