I got this question during an interview.

Origin of the question is Aeration and Agitation topic in section Aeration and Agitation of Fermentation Technology

Answer 1

The correct answer is (c) Industrial to pilot-scale

To elaborate: The scale-up process involves increasing the scale of fermentation by performing the experiments at laboratory or pilot scale and build large-scale fermenters with sufficient confidence that it will function properly.
