If accretion of planetesimals had not generated enough heat, which explanation of Earth's internal structure would be most weakened?

Answer and explanation

Correct answer: Density-based differentiation and the formation of the core

The correct answer is A. Heat generated during accretion helped melt material inside the early Earth. In the resulting mobile material, denser substances could sink and lighter substances rise, leading to differentiation and core formation.
