Fermentation is the process which is carried by anaerobic respiration of microorganism which leads to the production of lactic acid or alcohol with the release of carbon dioxide. When the yeast is added to the dough of the bread it converts the sugar to ethanol and carbon dioxide which forms bubbles and leads to the expansion of the dough.
So, the correct answer is option D.
