When a galvanometer is shunted with a 4O...

When a galvanometer is shunted with a `4Omega` resistance, the deflection is reduced to `1//5`. If the galvanometer is further shunted with a `2Omega`. wire, the new deflection will be (assuming the main current remains the same)

A

`1//13` of the deflection when shunted with `4Omega` only

B

`8//13` of the deflection when shunted with `4Omega` only

C

`3//4` of the deflection when shunted with `4Omega`only

D

`3//13` of the deflection when shunted with `4Omega`only
