Question

dissociative disorders can appear when:
a. a person experiments with drugs.
b. a person is under excessive stress.
c. a person has had an accident.
d. a person associates with another person with the disorder.

Explanation:

Dissociative disorders are often linked to excessive stress, especially trauma - related stress. Drug experimentation (A) isn't a primary cause. Accidents (C) may cause trauma but the key trigger for dissociative disorders is the stress from such events, and they aren't contagious via association (D). So excessive stress (B) is the main cause.

Answer:

B. a person is under excessive stress.
