You have answered 4 out of 4 correctly.
1. "In DSM-V, the main difference between acute stress disorder and PTSD is the length of presence of symptoms. (Acute stress disorder - within 4 weeks; PTSD - more than 4 weeks)."
Statement 1 is true. In DSM-V, acute stress disorder and PTSD were deemed to have similar presentation of clinical symptoms, the only major difference is acute stress disorder last from 2 days up to 4 weeks, and PTSD is diagnosed when symptoms last for more than 4 weeks.
2. "In ICD-10, onset of PTSD symptoms must occur within 4 months of traumatic events."

4. "In both ICD-10 and DSM-V criteria, acute stress disorder mostly diminish within 48 hours."
