Solution
The correct option is B Yeast cells
The species of yeasts which is commonly used for baking is Saccharomyces cerevisiae and thus known as baker's yeasts. The yeast cells perform fermentation reactions. In these reactions, the fermentable sugars are converted to ethanol and carbon dioxide. The yeast cells are added to the dough of idli, bread and cake. The carbon dioxide produced makes the dough to rise and become more soft and fluffy. This makes the fermented foods porous due to the trapping of carbon dioxide bubbles during baking. Thus, the correct answer is option C.
