Choose the WRONG statement. The sensitivity of a moving coil galvanometer can be increased by

Sensitivity of a moving coil galvanometer can be increased by increasing the number of turns in the coil, Increasing strength of the magnetic field in-order to have a significant deflection. And adding soft iron will increase sensitivity because the magnetic lines of force can be attracted by the soft iron core

Having a suspension fibre of a higher restoring couple will decrease the sensitivity of the galvanometer.
