Understanding the Answer
Let's break down why this is correct
The umbra is the darkest part of the shadow when the Moon directly blocks all sunlight from reaching the Earth. Other options are incorrect because A lighter shadow zone lets only part of the Sun’s light through, so you still see a bright disk; When the Moon is farther away, it appears smaller, so the Sun is not completely blocked and a ring of light remains.
