Answer:
C. a portion of the Moon passes through Earth’s shadow
Explanation:
A lunar eclipse occurs when the Sun, Earth and the Moon lie in a straight line with Earth between the Sun and the Moon.
Moon does not have its own light. It is illuminated by the sunlight. When the Earth comes between the Sun and the Moon, it blocks the sunlight falling on moon and a lunar eclipse is said to occur.
A total lunar eclipse occurs when the whole moon passes through the Earth's shadow. When a portion of moon passes through the Earth's shadow, a partial lunar eclipse occurs.
Thus, option c is correct.
