In an experiment of calibration of voltmeter, a standard cell of emf 1.5 is balanced at 375cm length of potentiometer wire. The P.d across a resistance in the circuit is balanced at 1.25m. If a volt meter is connected across the same resistance, it read 0.6v. The error in the voltmeter is

A

0.1V

B

0.025V

C

0.235v
