Evan sees a lunar eclipse one night. When he briefly observes the Moon, about half of it is bright and the other half is dark. He wonders what phase the Moon is in during this event.

Evan decides to use a model of the Sun-Earth-Moon system to determine the Moon's phase during a lunar eclipse. He uses a light bulb to represent the Sun and its light, a softball to represent the Earth, and a golf ball to represent the Moon.



Which diagram shows how Evan should arrange his model to investigate a lunar eclipse?
