Question

1. fermentation is a key component in the process of fuel production known as ______.

○ detoxification
○ hydroxylation
○ refinement
○ bioconversion

Explanation:

Fermentation is a biological process that converts organic materials (like sugars) into fuels (e.g., bioethanol), which falls under bioconversion. Detoxification removes toxins, hydroxylation adds hydroxyl groups, and refinement is a general fuel processing step not centered on fermentation.

Answer:

O bioconversion
