Solution

The correct answer is Amnesia. Amnesia is a medical condition characterised by partial or total loss of memory. It's often caused by brain injury or disease. Ambrosia: This is a mythical food of the gods, unrelated to memory loss. Insomnia: This is a sleep disorder characterised by difficulty falling asleep or staying asleep. Forgetting: While this is a general term for the act of not remembering, it doesn't capture the specific medical condition of memory loss.
