I agree.

To determine the correct answer, let's break down the question.

The question asks about the potential effects of a poor diet on the child of teenage mothers who are accustomed to eating hamburgers, French fries, and Cokes. The options provided are:

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

To find the answer, we need to consider the information given in the question and evaluate each option.

Option A suggests that a poor diet can restrict the development of eye and hair color. While nutrition can affect overall health, eye and hair color are determined by genetics and not impacted by diet. Therefore, option A can be ruled out.

Option B proposes that a poor diet can produce prenatal hearing loss. While proper nutrition is important during pregnancy to support the baby's development, there is no direct link between a poor diet and prenatal hearing loss. Thus, option B can be eliminated.

Option C suggests that a poor diet can have adverse effects on the child's mental development. This option aligns with research, as studies have shown that inadequate nutrition during pregnancy and early childhood can result in cognitive and developmental issues in children. Therefore, option C is a valid possibility.

Option D states that a poor diet can make delivery difficult for the mother. While a poor diet may have an impact on the mother's health, it is not directly related to the difficulty of delivery. Therefore, option D is unlikely.

Considering all the information, you were correct in choosing option C. A poor diet can indeed have adverse effects on the child's mental development.
