Fermentation is a process of anaerobic catabolism. It is the continuation of glycolysis in the absence of oxygen. During fermentation, pyruvate is metabolized to ethanol, carbon dioxide and 2 molecules of ATP.
Alcohol can be produced by the fermentation of sucrose by the baker's yeast. Initially, the organism reproduces by aerobic respiration, if all the available oxygen is utilized, then the organism starts fermentation.
Baker's yeast is used in the preparation of the bread for fermentation. Cheese is a fermented milk product.
Thus, the options (a), (b), and (c) are incorrect.
Orange juice is prepared by crushing the peeled fresh oranges. It does not include the fermentation process.
Hence, the correct answer is
