Identify the abnormal behaviour referring to the 4 D's -

Reema was laughing loudly at her mother's funeral, running up and down the stairs, throwing objects at the gathered mourners

Based on the four Ds of abnormal behavior - deviance, distress, dysfunction, and danger - the abnormal behavior in the given scenarios is Reema's behavior at her mother's funeral.

Deviance: Reema's behavior of laughing loudly, running up and down the stairs, and throwing objects at the gathered mourners is deviant from the expected behavior at a funeral. Funerals are typically solemn events where people express their grief and respect for the deceased. Reema's behavior is not in line with these expectations.

Distress: Reema's behavior is also likely to cause distress to the other mourners at the funeral. Her laughter and disruptive behavior are likely to be upsetting and disrespectful to those who are grieving.

Dysfunction: Reema's behavior is also interfering with the normal functioning of the funeral. It is making it difficult for others to mourn and say goodbye to the deceased.

Danger: Reema's behavior is also potentially dangerous. She is throwing objects, which could injure someone. She is also running up and down the stairs, which could cause her to fall and injure herself or someone else.

The other behaviors described in the scenarios are not as clearly indicative of abnormal behavior. Monica talking to herself while praying may be considered unusual, but it is not necessarily a sign of distress or dysfunction. Seema waving her arms mechanically in the middle of the road is unusual, but it is clearly related to her job as a traffic police woman. Sheeba dancing with joy in a restaurant is not deviant, distressing, or dysfunctional.
