A galvanometer has a resistance G and current `I_(a)` flowing in it. Produces full scale deflection. If `S_(1)` is the value of shunt which converts it into an ammeter of range O-0i and `S_(2)` is the value of the shunt for the range 0.2 i, then the ratio `(S_(1))/(S_(2))` will be:

A

`(1)/(2)((I-I_(g))/(2I-I_(g)))`

B

`(2I-I_(g))/(I-I_(g))`

C

`1//2`

D
