Explanation:

The Earth's physical shape is an oblate spheroid. A sphere (option A) is a simplified model, "round" (option B) is a general term, "flat" (option C) is incorrect, and "doughnut" (option E) is not accurate. The oblate spheroid (option D) accounts for the slight flattening at the poles and bulging at the equator due to Earth's rotation.
