Explanation

Fermentation is the process of anaerobic respiration, which is carried out by some fungi and bacteria. Fermentation also occurs in muscles of higher vertebrates. In these tissues, it is lactic acid fermentation. Fungi and bacteria carry out alcoholic fermentation (yeast).

C Correct answer
Explanation

Respiration is the catabolic process in which reduced substrates are broken down. The process of respiration can occur in presence of oxygen (aerobic respiration) or absence of oxygen (anaerobic respiration). The process of anaerobic respiration is also called as fermentation. In some microorganisms like yeast, the process of anaerobic respiration (fermentation) results in incomplete breakdown of glucose to ethanol and carbon dioxide.
