By what name is the early disk in the formation of the solar system known?

Answer and explanation

Correct answer: Solar disk

The early rotating disk of gas and dust surrounding the young Sun is called the solar nebula or protoplanetary disk. In the wording of this question, “solar disk” is the intended name, so option A is correct. Material in this disk moved around the forming Sun, collided, and gradually accumulated into larger bodies that eventually became planets, moons, asteroids, and other objects. The forest, water, and rock cycles are Earth-system concepts and do not describe the disk from which the solar system developed. A precise scientific treatment may distinguish the solar nebula from the later protoplanetary disk, but among these choices A is the only relevant answer.
