A glavanometer of `50 Omega` resistance has 25 divisions. A current of `4xx10^(-4)` A gives a deflection of one division. To convert this galvanometer into a voltmeter having a range of `25 V`, it should be connected with a resistance of
A. `2500 Omega` as a shunt
B. `2450 Omega` as a shunt
C. `2550 Omega` in series
D. `2450 Omega` in series
