Solution

The correct option is C the current it measures.
Sensitivity of galvanometer is defined as the current in micro ampere required to consume one millimeter deflection on a scale placed 1m away from the mirror.
Now we know that : $I = \frac{C θ}{B N A}$ where $C =$ torque per unit twist, $θ =$ Angle of twist, $B =$ Strength of the magnetic field, $N =$ Number of turns in the coil and $A =$ area of coil.
Thus the sensitivity of galvaometer will not depend on the current it measures.

Moving coil galvanometers are of two types
(i) Suspended coil
(ii) Pivoted coil type or tangent galvanometer,

Its working is based on the fact that when a current carrying coil is placed in a magnetic field, it experiences a torque. This torque tends to rotate the coil about its axis of suspension in such a way that the magnetic flux passing through the coil is maximum.
