carbohydrates and fats are both
○ used as energy sources.
○ indigestible unless they are consumed together.
○ sources of amino acids.
○ digested and absorbed in the human stomach.

Explanation:

• Analyze each option:
• "used as energy sources": Carbohydrates are the primary energy source, and fats are a stored energy source. This is correct.
• "indigestible unless they are consumed together": Both can be digested separately (e.g., carbs in mouth/stomach, fats in small intestine), so this is wrong.
• "sources of amino acids": Amino acids come from proteins, not carbs or fats. Wrong.
• "digested and absorbed in the human stomach": Carbohydrates start digestion in the mouth, fats are mainly digested in the small intestine. Stomach doesn't absorb most nutrients. Wrong.

Answer:

A. used as energy sources.
