**Moon: The Natural Satellite**

The correct answer to the given question is option 'C', which is the Moon. The Moon is a natural satellite that orbits around the Earth. It does not emit light of its own, but rather reflects the light of the Sun, making it visible in the night sky.

**Explanation:**

The Moon is Earth's only natural satellite and an essential part of our night sky. Here's a detailed explanation of why the Moon is the correct answer:

1. **Natural Satellite:** The Moon is often referred to as a natural satellite because it orbits around a planet, in this case, the Earth. It is not a star or the Sun, which eliminates options 'A' and 'B' as correct answers.

2. **Reflects Sun's Light:** Unlike stars that emit light due to nuclear reactions or the Sun, which generates its own light and heat through nuclear fusion, the Moon does not emit light. Instead, it reflects the light of the Sun. This reflection makes the Moon visible to us on Earth.

3. **Visible in the Night Sky:** The Moon is most commonly observed in the night sky. During the day, the Sun's brightness outshines the Moon, making it difficult to see. However, as the Sun sets and darkness falls, the Moon becomes more visible. Its reflection of sunlight allows us to see its bright surface and various phases.

4. **Earth's Moon:** The Moon is specifically associated with the Earth. It is Earth's natural satellite and has a significant impact on our planet. It affects ocean tides, helps stabilize Earth's axial tilt, and has played a crucial role in the development of life on our planet.

In conclusion, the Moon is a natural satellite that orbits around the Earth, reflects the light of the Sun, and is visible in the night sky. It is not a star or the Sun, making option 'C' the correct answer.

Moon is a natural satellite which does not emit its own light but reflects the light of the Sun falling on it.
