Answer:

3) At the time of a full moon

Explanation:

Lunar nodes are the locations where the Moon crosses the Earth's orbital plane. Total lunar eclipses happen only when: It is Full Moon. At the same time, the Moon is at (or very near) a lunar node, so the Sun, the Moon, and the Earth are aligned in a straight (or nearly straight) line.
