Which of the following is an argument against a strictly biological explanation of postnatal mood disorders?

A) There is little relationship between hormone levels and mood.
B) Postnatal hormone changes are minimal.
C) Hormones do not give rise to bodily sensations.
D) None of these answers is correct.

There is evidence that hormone levels can play a role in postnatal mood disorders, but the relationship is not always clear or consistent. Factors such as life stressors, social support, and individual experiences may also contribute to the development of mood disorders, indicating a more complex explanation beyond strictly biology.
