Teenage mothers who are accustomed to existing on hamburgers, French fries, and
cokes need to consider the nutritional needs of the child. Research has shown that
a poor diet can:
a. restrict the development of eye and hair color.
b. produce prenatal hearing loss.
c. have adverse effects on the child's mental development.
d. make delivery difficult for the mother.
I think that's C can be right answer,but i'm not sure:)
