Yeast breads are breads:

• A. Leavened with baking soda
• B. Leavened with sourdough starter
• C. Leavened with yeast and require a longer rising time
• D. Leavened with baking powder

Answer: (C)

Yeast breads rely on yeast fermentation to produce carbon dioxide, which inflates the dough and builds its structure. This process takes time, so these breads usually undergo longer rising periods to allow the yeast to metabolize sugars, create gas, and develop flavor and gluten strength. Quick breads, in contrast, use chemical leaveners like baking soda or baking powder that react quickly and don’t need long rises. A sourdough starter can be used to leaven some breads because it contains wild yeast, but not all yeast breads depend on a starter; they can be leavened with commercial yeast as well. So the defining characteristic is that they are leavened with yeast and require a longer rising time.
