Correct Answer: Option B
Explanation:
The correct answer is B: fermentation.

Starch can be converted into ethyl alcohol (ethanol) through a process called fermentation. Here's how it works:

1. Hydrolysis: Starch is first broken down into simpler sugars (such as glucose) by enzymes like amylase.
2. Fermentation: The glucose is then fermented by yeast, which converts the sugars into ethanol (ethyl alcohol) and carbon dioxide.

So, fermentation is the process that converts starch into ethanol.
