Understanding the Answer
Let's break down why this is correct
Answer
Umbra is the darkest part of a shadow, where the Sun is completely hidden, so an umbral eclipse is a total solar eclipse. Penumbra is the lighter, outer part of the shadow, where only part of the Sun is covered. Thus a penumbral eclipse is a partial solar eclipse, where the Sun is only partially obscured. In this case the Sun still shows a bright crescent or ring, showing the gradual reduction in light. So the analogy is: Umbra: Total Solar Eclipse :: Penumbra: Partial Solar Eclipse.
Detailed Explanation
The penumbra is the outer part of the Earth’s shadow, where the moon covers only part of the sun. Other options are incorrect because A lunar eclipse occurs when Earth sits between the sun and the moon, darkening the moon, not the sun; The penumbra still creates a shadow; it does not mean no eclipse happens.
