C. It was released as CO2 and H20

Explanation:

During fat metabolism, the products are CO2 AND H20. The carbon dioxide is exhale and the water mixes into circulation system until it's lost as urine or sweat.

Fat metabolism do not yield amino acids. Amino acids are from the breakdown of protein. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.

Correct answer is C. It was released as CO2 and H20.
