16. During a lunar eclipse (A) the Moon lies between the Earth and Sun (B) the Sun lies between the Moon and Earth (C) the Earth lies between the Moon and Sun (D) the Sun lies outside the Moon's umbra

The correct answer is (C) the Earth lies between the Moon and Sun.<br /><br />During a lunar eclipse, the Earth is positioned directly between the Sun and the Moon, causing the Earth to cast its shadow on the Moon. This alignment results in the Moon appearing darkened or partially obscured, depending on the extent to which it enters the Earth's umbra (the central, darkest part of its shadow) or penumbra (the outer, lighter part of its shadow).
