Context: The passage below describes an experiment. Read the passage and then follow the instructions below.

Brody made six batches of muffins over the course of one day. He used whole wheat flour in three of the batches and white flour in the other three batches. He divided the batter into muffin tins, using two ounces of batter per muffin. He baked the muffins in a 350°F oven for 20 minutes. After allowing the muffins to cool, Brody measured the dimensions of the muffins and calculated their volumes. He compared the volumes of the muffins made with whole wheat flour to the volumes of the muffins made with white flour.
Figure: muffins cooling.
Identify the question that Brody's experiment can best answer.
A. Does the type of flour used in the muffins affect the number of muffins that turn brown after 30 minutes in the oven?
B. Do muffins made with white flour have larger volumes than muffins made with whole wheat flour?
Select the correct answer from the given choices and respond with the letter of the chosen option.
