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

`(R(S_(1)+S_(2)))/(S_(1)S_(2))`

B

`(S_(1)S_(2))/(R(S_(1)+S_(2)))`

C

`(RS_(1)S_(2))/((S_(1)+S_(2)))`

D

`((S_(1)+S_(2)))/(RS_(1)S_(2))`
