The process of accretion in planetary formation is the A) slow condensation by gravity of gas atoms into large, dense gas clouds that are the preplanetary masses. B) slow acquisition from deep space by the giant planets of their complement of moons by gravitational capture. C) slow accumulation of solid particles by gravity and collision into larger, solid objects. D) relatively rapid gravitational collapse (in less than 10⁶ years) of gas clouds to form planets.

The process of accretion in planetary formation involves the slow accumulation of solid particles by gravity and collision into larger, solid objects. This is a key mechanism in the early stages of planetary formation, where dust and small particles gradually come together to form larger bodies, eventually leading to the formation of planets.
