C Correct answer
Explanation

Respiration is the process where living organisms use oxygen to break down food, releasing carbon dioxide, water vapor, and energy. Option C incorrectly reverses this - claiming respiration uses CO2 and produces O2, which describes photosynthesis, not respiration. The statement 'uses carbon dioxide and produce oxygen' is the opposite of actual respiration.
