Answer 1

B: the lighter part of a shadow

Step-by-step explanation:

The penumbra is a lighter type of shadow. Like any other opaque objects illuminated by a light source, the Moon and the Earth cast shadows into space as they block the sunlight that hits them. Each shadow has 3 different areas: the umbra, the penumbra, and the antumbra.
