So, the correct options are b, c, and d.
- Oxygen (Option: d): Oxygen is essential for aerobic respiration as it serves as the final electron acceptor in the process.
- Enzymes (Option: b): Enzymes are crucial for facilitating the various reactions involved in aerobic respiration. They act as catalysts to speed up the chemical reactions.
- Organic molecules (Option: c): Organic molecules, such as glucose, are the main fuel source for aerobic respiration. These molecules are broken down during the process to produce energy.
Therefore, the correct options are d (oxygen), b (enzymes), and c (organic molecules).
