Solution

The correct option is C If assertion is true but reason is false
The magnetic field lines of the earth resemble that of a hypothetical magnetic dipole located at the centre of the earth. The axis of the dipole does not coincide with the axis of rotation of the earth but is presently titled by approximately ${11.3}^{0}$ with respect to the later
