What is the most accurate description of the shape of the earth?

A circle Spheroid A sphere An oblate sphere

An oblate sphere

The correct answer is Option (4) - An oblate sphere The shape of the earth seems like a sphere, although it is not perfectly spherical. It is rather an oblate spheroid because of the earth's diurnal rotation, i.e, the earth is slightly flattened at its polar ends and bulged out at the equatorial part.
