The wire in the potentiometer has a resistance of R0 and the potentiometer is connected to a battery of voltage 'V'. Now a resistor 'R' whose value of resistance has to be measured is connected. When the sliding point is exactly in the middle of the potentiometer, the voltage drop across 'R' is V/4. What is the value of R/R0?

A) 1/4           B) 4                C) 2              D) 1/2
