B

If both assertion and reason are true and reason is not the correct explanation of assertion.

C

If assertion is ture but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C
The magnetic field lines of the earth resemble that of hypothetical magnetic dipole located at the centre of the earth. 'Ice a)ds of the dipole does not coincide with the axis of rotation of the earth but is presently tilted by approximately `11.3^(@)` with respect to the late
