In a Wheatstone's bridge, three resistances P,Q and R connected in the three arms and the fourth arm is formed by two resistances `S_1 and S_2` connected in parallel. The condition for the bridge to be balanced will be

A

`(P)/(Q)=(2R)/(S_(1)+S_(2))`

B

`(P)/(Q)=(R(S_(1)+S_(2)))/(S_(1)S_(2))`

C

`(P)/(Q)=(R(S_(1)+S_(2)))/(2S_(1)S_(2))`

D

`(P)/(Q)=(R)/(S_(1)+S_(2))`
