Explanation:

Let's examine each answer choice.

A. The molecules get destroyed.

This is false. Matter can't be destroyed.

B. The molecules are converted to energy and other molecules.

This choice is true. Different molecules are used for different purposes.

C. The molecules get completely eliminated by the rabbit as waste.

This is false. Nutrients and molecules are extracted and used in the body for processes like cellular respiration.

D. The molecules are converted to energy only.

This is false. Some molecules will be used to produce ATP, but not all. Some will be used in other processes and eliminated as waste.

The best answer is Choice B.
