Which of the following, if true, would most strongly support the position above?
A: Cereals containing vitamin supplements are no harder to digest than similar cereals without added vitamins.
B: People who regularly eat cereals fortified with vitamin supplements sometimes neglect to eat the foods in which the vitamins occur naturally.
C: Unprocessed cereals are naturally high in several of the vitamins that are usually added to fortified breakfast cereals.
D: In many foods, the natural combination of vitamins with other nutrients makes those vitamins more usable by the body than are vitamins added in vitamin supplements.
