• A. A severe anxiety disorder that develops after experiencing or witnessing extremely stressful events.
• B. A mood disorder that improves with time.
• C. A learning disability.
• D. A personality disorder.

Answer: (A)

Post-traumatic stress disorder is a severe anxiety disorder that develops after experiencing or witnessing extremely stressful events. In police work, this can follow critical incidents such as shootings, line‑of‑duty injuries, fatalities, serious accidents, or natural disasters. People with PTSD may experience intrusive memories like distressing flashbacks or nightmares, avoidance of reminders of the event, negative changes in thoughts or mood, and heightened arousal such as hypervigilance or an easy startle response. These symptoms persist for more than a month and cause significant distress or impairment in daily functioning, including work performance and relationships. Diagnosis involves confirming that the symptoms are related to the trauma, cause noticeable impairment, and are not better explained by substances or another medical condition. Treatment is effective and often includes trauma-focused therapies (such as cognitive processing therapy or prolonged exposure) and sometimes medications to manage symptoms.

The other options don’t fit because PTSD is not merely a mood disorder, a learning disability, or a personality disorder. A mood disorder centers on persistent disturbances in mood; a learning disability affects how someone processes information and learns; a personality disorder involves enduring patterns of behavior and experience, not specifically tied to traumatic exposure.
