The answer is A
That's when we have a lunar eclipse.
"Umbra" means "shadow". When the Moon enters the Earth's shadow, we call that a "total lunar eclipse".
When the moon is hidden by Earths shadow it's just on the other side of Earth. Making it night for the other side of the planet. Also or when it is hidden it just is called the New Moon. This part of moon changing happens every month.
During a lunar eclipse, the Earth's shadow on the Moon is round, as the Earth blocks the sunlight from reaching the Moon. The shadow appears to move across the face of the Moon during the eclipse, creating a partial or total eclipse depending on the alignment of the Earth, Moon, and Sun.

That's when we have a lunar eclipse.
The moon darkens because it passes through Earths shadow.
The moon will go orange/red during a lunar eclipse, as the earths atmosphere distores the light from the sun.
The Earth is larger than the Moon.
The umbra ans penumbra
A lunar eclipse is where the Earth comes between the moon and sun, so that light to the moon is blocked out by Earths shadow. A solar eclipse is where the moon comes between the sun and Earth, blocking out sunlight to the Earth.
The moon remains partly visible during a lunar eclipse because light is refracted round the earth by its atmosphere. A lunar eclipse is when the moon passes through earths shadow. A partial eclipse,is when only part of the moon is in earths shadow.Then the moon might look like something took a bite out of it.Unlike a partial eclipse,a total luna eclipse occurs whe the whole moon is in the earths shadow.The moon does not disappear during a lunar eclipse.Earths atmosphere bends and scatters some sunlight,allowing some of the suns rays to reach the moon.Lunar eclipses happen several times a year.
"Umbra" means "shadow". When the Moon enters the Earth's shadow, we call that a "total lunar eclipse".
