Which option most accurately matches each theory with its scale of explanation?

Answer and explanation

Correct answer: Big Bang—universe; solar nebula—solar system; differentiation—Earth’s internal structure

The governing concept is matching an origin theory to the spatial scale and process it explains. The Big Bang concerns the origin and expansion of the universe, so its scale is cosmic. The solar-nebula model explains how material around the young Sun formed the solar system. Differentiation describes how heavier and lighter materials separated inside the young Earth, helping produce internal layers. Therefore option A correctly matches all three. Options B, C and D attach these theories to rivers, weather, agriculture, life or isolated crustal features, which are not their proper explanatory scales. Careful scale matching prevents confusing cosmic, planetary-system and Earth-interior processes.
