Explanation:

Question 7

Leavening agents cause dough or batter to rise. Yeast ferments sugars to produce carbon dioxide. Baking soda (\(NaHCO_3\)) reacts with acids to release \(CO_2\). Baking powder is a combination of baking soda and an acid salt. Sugar (\(C_{12}H_{22}O_{11}\)) does not produce gas to leaven.

Room temperature in cooking context is a standard range. Heating to 350°F is oven temperature. Partially frozen and chilled but not frozen are lower than typical room - temp. Approximately \(68 - 72^{\circ}F\) is the common range for room temperature.

Answer:

B. sugar
