Quizplus · Accepted Answer

When we say that the terrestrial worlds underwent differentiation, we mean that during their formation, their interiors were molten, and denser materials sank toward their centers while lighter materials rose toward their surfaces. This means that the layered structures of these worlds were established early on in their history.

Option B talks about how the terrestrial worlds ended up looking different, but it does not explicitly refer to differentiation. Option C refers to the diversity of geological features on their surfaces, but this is not specifically related to differentiation. Option D describes how the worlds lost interior heat but does not relate to their formation and differentiation.
