Explanation:

- Option 1: Phosphorus

- Phosphorus is a mineral that plays a critical role in the body but is not involved in the rising process of bread dough.

- Option 2: Nitrogen

- Nitrogen is a gas that makes up a large portion of the Earth's atmosphere, but it does not contribute to the rising of bread.

- Option 3: Oxygen

- Oxygen is essential for yeast respiration initially but does not create bubbles in the dough.

- Option 4: Carbon Dioxide

- Correct Answer

- Yeast ferments the sugars in the dough, producing carbon dioxide gas. This creates thousands of bubbles, making the dough rise.
