Which process occurs only under anaerobic conditions?
A
Krebs cycle
B
Fermentation
C
E.T.C.
D
Glycolysis
Explanation: 

Detailed explanation-1: -Answer and Explanation: Fermentation can be observed in the anaerobic condition only. When there is deprivation of the oxygen molecules in the human cell (mostly in the muscle cells), the body produces lactic acid.

Detailed explanation-2: -Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis. One type of fermentation is alcohol fermentation.

Detailed explanation-3: -Lactic acid fermentation The fermentation of lactic acid or lactate fermentation is an anaerobic process that takes place in the cytoplasm of the cells. In this process, the enzyme converts the pyruvic acid produced in glycolysis into a three-carbon molecule called lactic acid.
