`AB` is a potentiometer wire of length `100 cm` and its resistance is `10 ohms`. It is connected in series with a resistance `R = 10 ohms` and a battery of e.m.f. `2 V` and negligible internal resistance. If a source of unknown e.m.f. `E` is balanced by `40 cm` length of the potentiometer wire, the value of `E` is

A. `0.8V`
B. `1.6V`
C. `0.08V`
D. `0.16V`
