    Lunar eclipse
  2. Solar eclipseAnswer
  3. C

Answer

Solar eclipse
A solar eclipse takes place when the Moon passes directly between the Sun and Earth. Observers located within the shadow cast on Earth's surface see the Sun obscured and experience temporary darkness during the day.

Step-by-Step Solution

1
Analyze the celestial bodies and their relative positions described in the question.
The Moon positions itself directly between the Sun and Earth.
Identifying the object blocking the light source determines the type of astronomical event.
2
Determine where the shadow falls and what observers on Earth experience.
The Moon casts its shadow onto Earth during the day, temporarily blocking sunlight.
An event where sunlight is blocked by the Moon during daytime corresponds to a solar eclipse.

Key Concept

Solar eclipses occur when the Moon is positioned directly between the Sun and Earth, blocking solar illumination from reaching portions of Earth.
