Final answer:
The Earth completely blocks the sun from the moon's view during a total solar eclipse seen from the Moon. It happens when the Earth is between the Moon and the Sun, and it’s similar to experiencing a lunar eclipse but from the lunar perspective.
Step-by-step explanation:
The best description of a total solar eclipse seen from the Moon would be (b) The Earth completely blocks the sun from the moon's view. During a total solar eclipse, the Moon moves between the Sun and Earth, casting its umbra, the darkest shadow, upon Earth's surface. This shadow is where the solar disk is entirely obscured by the Moon. If one is directly within this small point of the umbra, they will experience the total eclipse, where the Sun's light is completely blocked, and the solar corona becomes visible.
When this happens, from the Moon's perspective, the Earth would be in between the Moon and the Sun, blocking the Sun's light and causing what is essentially a lunar eclipse but seen from the moon. Unlike a partial eclipse, a total eclipse completely hides the bright disk of the Sun.
