In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level effective gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh about 0.5% more at the poles than at the Equator.

'A' option is correct. Because g(acceleration due to gravity) is indirectly proportional to r (radius of earth). Distance from cente of earth to poles is less than to equator. Therefore, g is greater at the poles.
