If a galvanometer has full scale deflection current `I_(g)` and resistance G. A shunt resistance `R_(A)` is used to convert it into an ammeter of range `I_(o)` and a resistance `R_(V)` is connected in series to convert it into a voltmeter of range `V_(0)` such that `V_(0)=I_(0)G` then `R_(A)R_(V)` and `R_(A))/(R_(V))` respectively are:

A

`G^(2)` and `(I_(2)^(G))/((I_(0)-I_(G)^(2))`

B

`G^(2)` and `(I_(0)^(2))/((I_(0)-I_(G)^(2))`

C

`G^(2)` and `(I_(G))/((I_(0)-I_(g))`

D

`G^(2)` and `(I_(G)^(2))/((I_(0)+I_(G))^(2))`
