For Matthew, the marginal utility of the 9th soda in a day is positive and the marginal utility of the 10th soda in a day is zero. This


A) implies that Matthew's demand curve for sodas per day will become upward sloping at 10 sodas per day.
B) is impossible because each additional unit of consumption of any good must provide positive marginal utility.
C) implies that at a zero price Matthew's demand curve will intersect the quantity axis at 10.
D) implies that Matthew maximizes utility by consuming 9 sodas per day.
