Solution

The correct option is C Glucose to $C O_{2}$ and $H_{2} O$ by Saccharomyces.
Saccharomyces cerevisiae under anaerobic condition converts glucose into ethanol. The process is called as alcohol fermentation. Under anaerobic condition, Lactobacillus, facultative anaerobe converts lactose to lactic acid. This process is used to prepare yogurt. This is called as lactic acid fermentation. Anaerobic fermentation of cellulose by Cellulomonas, facultative anaerobe results in the formation of glucose. Under aerobic condition, Saccharomyces utilizes glucose and oxygen to produce energy along with CO $_{2}$ and water.
Thus, the correct answer is option C.
