B
if both Assertion and Reason are true but the Reason is nor the correct explanation of the Assertion
C
if Assertion is true but Reason is false
D
if Assertion and Reason are false
Solution:
As a rotation of earth takes place about polar axis therefore, body places at poles will not feel any centrifugal force and its weight or acceleration due to gravity remains unaffected.
