  2. Lactic acid and Water
  3. Glucose and Oxygen
  4. Acetic acid and Nitrogen

Correct answer and explanation

Correct answer: Ethanol and Carbon dioxide

Explanation: āœ… Correct Answer: A) Ethanol and Carbon dioxide šŸ“š Explanation: Fermentation is a form of anaerobic respiration (occurring without oxygen).
