Explanation
The shape of the Earth is B: Ellipsoid.
An ellipsoid is a three-dimensional geometric shape that looks like a stretched-out sphere, with three axes of differing lengths. The shape of the Earth is not a perfect sphere, but rather an oblate spheroid, which means it is slightly flattened at the poles and bulging at the equator. This is due to the Earth's rotation, which causes the planet to bulge at the equator and flatten at the poles.
The shape of the Earth has been studied and measured extensively by scientists and geographers, and the precise shape has been determined through satellite imagery, global positioning systems (GPS), and other advanced technologies. The Earth's shape has significant implications for various fields, such as astronomy, geodesy, and cartography, as it affects how we measure distances and make accurate maps.
