Correct Answer: Maida and Yeast

Solution : The correct answer is Maida and Yeast.

The essential component in bread is flour, which gives the loaf its structure and texture. Wheat flour is the most often used form of flour for bread baking, however other types of flour, such as rye flour and whole wheat flour, can also be used.  Yeast is a live organism that produces carbon dioxide gas by fermenting the carbohydrates in flour. Because of this gas, the dough rises, resulting in a light and fluffy loaf of bread.
