Answer 1

The correct option is C

growth of yeast cells

The correct option is (C):
Explanation for the correct option:

1. Yeast is widely used in cake and bread preparation because it converts the sugar in the dough to carbon dioxide.
2. The yeast cells grow and release carbon dioxide, which fills the dough and increases its volume.
3. Due to the heat, more gas bubbles emerge when this dough is baked.
4. The bread rises and becomes soft and fluffy as the gas leaves.

Final answer: The bread or idli dough rises because of growth of yeast cells.
