. When a galvanometer is shunted with

a 4W resistance, the deflection is reduced to one-fifth. If the galvanometer is further shunted with a 2W wire, the further reduction in the deflection will be (the main current remains the same).

A. (8/13) of the deflection when shunted with 4W only

B. (5/14) of the deflection when shunted with 4W only

C. (3/4) of the deflection when shunted with 4W only

D. (3/13) of the deflection when shunted with 4W only
