What is the correct reason for calling respiration an exothermic chemical reaction?

Answer and explanation

Correct answer: Energy is released when glucose is oxidised during respiration.

Respiration is an exothermic chemical process because glucose is oxidised in cells, generally represented as glucose plus oxygen forming carbon dioxide and water, with energy released for cellular work. The release of energy is the reason for the classification, so option A is correct. Freezing is unrelated to respiration, oxygen does not form a precipitate in this process, and carbon dioxide does not turn into a metal; therefore B, C, and D are impossible distractors.
