Final answer:
The statement is true; observations of asteroids, comets, and meteorites are crucial for refining theories about the solar system's formation. These remnants impose constraints that aid in understanding motion, chemical composition, and age, which in turn influence solar system formation theories.
Step-by-step explanation:
Observations of asteroids, comets, and meteorites do indeed help refine the theory of the formation of the solar system; therefore, the correct answer to the student's question is a) True. These celestial bodies are considered as the surviving remnants from the processes that formed the solar system. The information gathered from them contributes to the understanding of various aspects such as motion, chemical composition, and age of the solar system, and thus, they are invaluable in confirming or challenging theoretical models.
A robust theory of solar system formation must account for motion constraints, chemical constraints, and age constraints. The fact that these remnants -- comets, asteroid, and meteorites -- still exist provides evidence of the early solar system's conditions. These bodies offer critical clues about the composition and behavior of the solar nebula from which the Sun and planets condensed approximately 4.5 billion years ago.
