When the bread rises and bakes, ______creates thousands of bubbles in the dough.

carbon dioxide

The correct answer is Option (4)-carbon dioxide

When the bread rises and bakes, carbon dioxide creates thousands of bubbles in the dough.

Explanation:

During the process of bread fermentation, yeast (a type of fungus) ferments sugars present in the dough and produces carbon dioxide as a byproduct. The carbon dioxide gas gets trapped in the dough, causing it to rise. This process is crucial for making the bread light and airy. Additionally, the carbon dioxide expands further during baking, creating the characteristic texture of bread with a network of small bubbles. The production of carbon dioxide is a key step in leavening the bread, and it contributes to its volume and texture.
