O A. Prenatal exposure to viral infections can increase the likelihood of developing
schizophrenia.
B. Prenatal exposure to viral infections can increase the likelihood that twins will
be identical.
OC. Prenatal exposure to viral infections can decrease the likelihood of developing
schizophrenia.
O D. Prenatal exposure to viral infections has no relationship to the likelihood of
developing schizophrenia.

D)

Explanation:

A) is incorrect because the development of schizophrenia in pregnancy, while the mother, is having flu is not possible. Also B) and C) are the incorrect answers since the flu has nothing to do with the possibility of will the twins be

identical.

If a mother was having flu during pregnancy there is a possibility that it can affect a baby which means that it can cause birth deffects in a baby.
