C.

D.

C. Solar System

The correct answer is C. Solar System.

To arrive at this answer, we need to understand what a solar system is. A solar system is a collection of celestial objects, including planets, moons, comets, and asteroids, that orbit around a star. In our case, our solar system is named after our star, which is called the Sun.

To eliminate the other options:

- Option A, the United States, is a country on Earth, but it does not refer to the entire collection of celestial objects.

- Option B, Earth, is our home planet, but it alone does not encompass all the celestial objects mentioned.

- Option D, orbits, is a term used to describe the circular or elliptical paths of celestial objects in space, but it does not refer to the entire system itself.

Therefore, the correct answer is C. Solar System, as it includes all the mentioned celestial objects.

The correct answer is C. Solar System. The Solar System consists of planets, moons, comets, and asteroids.
