Explanation:

Respiration is a biological process where glucose reacts with oxygen to release energy, carbon - dioxide and water. Combustion is a chemical process where a substance reacts with oxygen and releases heat and carbon - dioxide (among other products depending on the substance). Coal is a fuel for combustion but not a product of either respiration or combustion in general. Glucose is a reactant in respiration, not a product. Oxygen is a reactant in both processes, not a product. Carbon dioxide is a product of both respiration and combustion.

Answer:

E. Carbon dioxide
