Intensity of gravitational field of earth is maximum at?

A. Poles
B. Equator
C. Center of earth
D. Surface

Explanation:

The earth is an oblate spheroid, and that means it bulges out in the middle (the equator). That also means the poles end up a little closer to the center of gravity. That is why on the surface of the earth, at the poles the intensity of gravity is the maximum.
