Social stress is most likely to lead to mental illness if the stress

A) is chronic.
B) is an acute trauma.
C) is linked to a life event, rather than an ongoing situation.
D) is treated with antidepressants.
E) is treated with antipsychotics.

Chronic social stress, such as ongoing financial difficulties or social isolation, can lead to long-term changes in the brain that increase the risk of developing mental illness. Acute trauma may also lead to mental illness, but it is less likely to have a long-lasting impact if it is a one-time event. Treatment with antidepressants or antipsychotics may alleviate symptoms, but they do not address the underlying source of social stress, which may continue to contribute to mental illness if left unaddressed.
