Od
during a full moon



Answer :

Final answer:

Total lunar eclipses occur only during a full moon phase due to the Moon passing through Earth's shadow, resulting in a red appearance. New moons and third quarter moons are not times when total lunar eclipses would occur.


Explanation:

Total lunar eclipses occur when the Moon passes through Earth's shadow, resulting in the Moon appearing red during totality. This phenomenon can only happen during a full moon.

During a new moon, the Moon is not visible from Earth as the side illuminated by the Sun faces away from us, making it impossible for a lunar eclipse to occur during this phase.

Third quarter moons occur when the illuminated side is away from Earth, making it unlikely for a total lunar eclipse to happen during this phase.
