Kim is a successful lawyer who suddenly forgot who she is and most of the important details of her life after she survived a terrible car accident that killed three of her colleagues. Kim may be suffering from

A) bipolar disorder.
B) conversion disorder.
C) dissociative amnesia.
D) multiple-personality disorder.

Kim's loss of memory is likely due to dissociative amnesia, which is characterized by the sudden loss of personal identity and important personal information, often triggered by a traumatic event. Bipolar disorder involves fluctuations in mood and energy, while conversion disorder involves physical symptoms without medical explanation. Multiple-personality disorder, now known as dissociative identity disorder, involves the presence of two or more distinct personalities within an individual. While Kim may be experiencing other symptoms or disorders as well, based on the information given, dissociative amnesia is the most likely diagnosis.
