Answer:
Option D. Carbon dioxide and energy
Step-by-step explanation:
Respiration is the breaking down of food by the intake of oxygen to release carbon dioxide and energy needed for metabolic processes. This can be seen by the equation below:
C6H12O6 + 6O2 —> 6CO2 +6H2O + Energy
From the above equation, we can see that the products are carbon dioxide, water and energy needed for metabolic process.
From the options, only option D has the product.
