The fact that a person's body experiences abnormal functioning when lacking the chemical suggests that it is essential for normal bodily functions, indicating that it could be a vitamin. The other options do not necessarily indicate that the chemical is a vitamin. A) The presence of the chemical in other fruits and vegetables does not necessarily indicate that it is a vitamin.
