Which of the following statements is true of acute stress disorder?

A) It occurs six months after a traumatic event and tends to persist.

Acute stress disorder is a condition where individuals experience symptoms such as re-experiencing, avoidance, and hyperarousal after a traumatic event. It typically occurs within one month of the event and can last up to a month. However, if the symptoms persist beyond a month, the individual may develop post-traumatic stress disorder (PTSD). Option A is incorrect because acute stress disorder occurs within a month of the traumatic event, not six months after. Option B is incorrect because acute stress disorder does not lead to physical weakness or multiple organ failures. Option D is incorrect because acute stress disorder was never termed multiple personality disorder.
