C.
The molecules get converted to energy and other types of molecules.
D.
The molecules get destroyed in the animal's body.

Answer 1

C.

Food molecules are broken down and used to produce energy (ATP) and to build other molecules (cells, fats, proteins). Some atoms are excreted (CO2, water, urea) or lost as heat, but the molecules aren't simply destroyed.
