Answer is B.
A moving coil galvanometer is based on the principle that a current-carrying coil or loop placed in a region of a magnetic field experiences a torque.
Current sensitivity of a galvanometer defines the deflection produced in the coil per unit current supplied to the galvanometer. A high current sensitivity implies a larger deflection for each unit rise in current.
