A meter bridge is set-up as shown, to determine an unknown resistance X using a standard 10 ohm resistor. The galvanometer shows null point when tapping key is at 52 cm mark. The end corrections are 1 cm and 2cm respectively for the ends A and B. The determined value of X is
10.2 ohm
10.6 ohm
10.8 ohm
11.1 ohm
