A galvanometer has resistance G and current `I_(g)` produces full scale deflection. `S_(1)` is the value of the shunt which converts it into an ammeter of range 0 - I and `S_(2)` is the value of shunt for the range 0 - 2I. The ratio of `S_(1)` and `S_(2)` is

A

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

B

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

C

`1//2`

D
