Option (C) $\rightarrow$ C is incorrect as psychologists usually have trouble recognizing depression in men.
OPtion (D) $\rightarrow$ The focus of the passage is not on further implications of the signs of depression, so D is a far-fetched conclusion.
Only option (A) captures this idea correctly. Hence, (A) is the correct answer.
