Explanation:

The solar nebula was the initial cloud - like mass from which the Sun and other objects in the solar system formed. The Sun formed first from the densest part of the nebula. The inner planets formed from the accretion of smaller particles. Planetesimals are small bodies that aggregated to form planets. They formed after the Sun and before the full - fledged planets. So, the inner planets formed last among the given options as they were the result of the growth and aggregation of planetesimals.
