Show answer and explanation

Correct answer: (c) zymase

Explanation

Zymase, an enzyme from yeast, ferments glucose into ethyl alcohol: C6H12O6 → 2C2H5OH + 2CO2.

Maltase breaks maltose into glucose and invertase splits sucrose, so neither yields alcohol.

Diastase converts starch into maltose, not glucose into ethanol.
