Answer:

The two sources of heat in the Earth's interior are leftover heat from formation and radioactive decay (A).

Explanation:

First, make sure to read the question carefully. The question is where the heat comes from in the Earth's interior. The heat from inside the Earth comes from leftover heat from formation and radiactive decay of isotopes in the mantle and the crust in equal amounts. This internal heat drives most geological processes and causes tectonic plates to move. In contrast sunlight is the most powerful source of heat on the surface.
