A Galvanometer of resistance `50Omega` is connected to a battery of 3 volt along with a resistance of `2950Omega` in series. A full scale deflection of 30 divisions is obtained in the galvanometer. In order to reduce this deflection to 20 divisions, the resistance in series should be
Options:
(a) `6050Omega`
(b) `4450Omega`
(c) `5050Omega`
(d) `5550Omega`
