What does the "Solar system" consist of?

1. a. A developed ovule consisting of a protective coat stored food and an embryo

2. b. Any celestial body orbiting around a planet or star

3. c. The sun with the celestial bodies that revolve around it in its gravitational field

4. d. Accidental contact between two points in an electric circuit that have a potential difference

The correct answer is: c. The sun with the celestial bodies that revolve around it in its gravitational field

The solar system is fundamentally defined as the sun along with the celestial bodies that revolve around it, all of which are bound by the sun's gravitational pull. This includes not only the eight major planets but also their moons, dwarf planets, comets, asteroids, and other smaller celestial bodies. The sun acts as the central star, providing the necessary gravitational force that keeps these objects in orbit, which is a central aspect of what characterizes a solar system. The other options do not accurately describe the solar system. The first option refers to a biological structure, the second pertains to celestial bodies in general without specifying their relationship to the sun. The last option discusses electrical circuits, which is entirely unrelated to the concept of a solar system. Thus, the correct understanding encompasses both the sun and the various celestial bodies it influences through gravity.
