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

`2`
