To find the market demand for doughnuts at the price of 25 cents, we need to add up the quantity demanded by each of the three townspeople.

Market demand = Al's demand + Betty's demand + Carol's demand

Market demand = 9 + 2 + 5

Market demand = 16

Therefore, the market demand for doughnuts at the price of 25 cents is 16 doughnuts. The best choice is (C).
