Solution

The correct option is C Gas pressure will develop because of excessive $C O_{2}$
Fermentation is incomplete oxidation of food substances into alcohol or lactic acid with $C O_{2}$ gas and a small amount of energy being released. Both lactic acid and ethanol fermentation do not produce oxygen. Hence, fermentation in a closed vessel will develop higher gas pressure due to excessive $C O_{2}$ .
So, the correct answer is option D.
