Question

which positions of the earth, sun, and moon will show you a full moon at night?

Explanation:

A full moon occurs when the Earth is positioned directly between the Sun and the Moon. This alignment means the entire sunlit face of the Moon is visible from Earth, and this configuration is visible at night from our perspective on Earth.

Answer:

The second option (S → E with M on the opposite side of E from S: <img src="" alt="S (left, arrows pointing right), E in center of dashed circle, M on right side of E">)
