Symptoms of Post-Traumatic Stress Disorder include :

The correct answer is Option (3) → Recurrent dreams, flashbacks, emotional numbing

People who have been caught in a natural disaster, a bomb blast, a serious accident or a war often experience post-traumatic stress disorder (PTSD). Its symptoms vary widely but may include recurrent dreams, flashbacks, impaired concentration and emotional numbing: the person keeps reliving the event and feels dulled. Option (3) gives three of these symptoms.

Option (1) Emotional numbing, happiness, feeling of elation — Incorrect. Emotional numbing fits, but happiness and elation do not. A person who keeps reliving a trauma is distressed, not elated; good feelings are no part of the disorder.

Option (2) Flashbacks, feeling of elation, thoughts about ill health — Incorrect. Flashbacks fit, but elation does not, and constant thoughts about ill health mark illness anxiety disorder, a persistent preoccupation with developing a serious illness.

Option (4) Thoughts about ill health, happiness, flashbacks — Incorrect. Only flashbacks fit. Happiness is no symptom of a trauma, and worry about ill health belongs to illness anxiety disorder.
