Final answer:
Option (B), Dissociative Identity Disorder (DID) is commonly associated with early childhood sexual or physical abuse, serving as a coping mechanism for severe trauma.
Step-by-step explanation:
Early childhood sexual or physical abuse is a common feature among people suffering from Dissociative Identity Disorder (DID). Research has shown a significant correlation between early trauma and the development of DID, where the disorder serves as a coping mechanism to detach oneself from the trauma of the abuse. The long-term effects of child abuse can manifest in various psychiatric disorders, but DID is one of the disorders most commonly associated with early severe trauma, such as abuse.
