Question

select two risk factors for self-harming behavior

a. having never abused drugs or alcohol

b. being female

c. having bipolar disorder or schizophrenia

d. being a teenager or young adult

Answer 1

so a is the contrary to the question, we can eliminate that.
b is sexist and biased.
c is very plausible and likely.
d is an incorrect generalization.

so I'd go for c since those are mental illnesses 

Answer 2

It would be C because it deals with mental illness.
