Which of the following is not produced during anaerobic respiration in unicellular fungus?
(a) C₂H₅OH (b) H₂O (c) CO₂ (d) ATP

(b) H₂O

During anaerobic respiration (absence of oxygen), the unicellular fungus (yeast) breaks down the glucose into ethanol (C₂H₅OH) and carbon dioxide (CO₂) and releases energy in the form of ATP.

Hence water molecule (H₂O) is not released.
