  • The molasses which are used is diluted so that the activity of yeast cells is fast and the production of ethanol occurs at a rapid pace. 
  • If the process is slowed down, then the molasses must not have been diluted before the addition of the fermentation medium in the fermentor.
  • Thus, the correct answer is option B.
