A solar eclipse occurs when the moon directly blocks sunlight from reaching the Earth. During this event, the moon's position is aligned between the Earth and the Sun, which causes the Sun to be obscured, either partially or completely, depending on the observer's location. This unique alignment leads to a shadow being cast on the Earth, creating the phenomenon known as a solar eclipse. The capability of the moon to block sunlight is what distinguishes solar eclipses from other celestial events, such as lunar eclipses, where the positioning of the Earth, moon, and Sun leads to the Earth casting a shadow on the moon instead.

In summary, the correct choice reflects the direct interaction between the moon and sunlight, emphasizing the role of the moon as a blocker of solar light during a solar eclipse event.
