What does the Solar System consist of?

The Solar System consists of the Sun and eight planets that orbit around it, which is precisely what option C describes. The Sun, being the central star, provides the necessary gravitational force to keep these planets in their orbits. In addition to the eight planets, the Solar System also includes dwarf planets, moons, asteroids, comets, and other celestial bodies, but the key factor in defining the Solar System lies in the relationship between the Sun and the eight main planets—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

In contrast, the other options do not accurately reflect the structure of the Solar System. The first option mentions only the Sun and two planets, which is insufficient since there are actually eight planets. The second option incorrectly limits the content of the Solar System to Earth and its moons, excluding the broader array of planets and celestial bodies. The last option refers to the largest stars in the universe, which are unrelated to the composition of the Solar System itself, as it focuses specifically on our local cosmic environment centered around the Sun.
