Solution

The correct option is B Saccharomyces

The bioconversion of starch into ethanol is a two-step process. The first step is saccharification, where starch is converted into sugar using an amylolytic microorganism or enzymes such as glucoamylase and amylase. The second step is fermentation, where sugar is converted into ethanol using Saccharomyces cerevisiae.

So, the correct answer is 'Saccharomyces'
