Solution

The correct answer is concussion.

A concussion is a type of traumatic brain injury that occurs when a blow to the skull causes the brain to move within the skull. This movement can result in the brain experiencing a variety of symptoms, including loss of consciousness, confusion, dizziness, headaches, and memory disturbances. While the other options listed—CVA (cerebrovascular accident), contusion, and TIA (transient ischemic attack)—are all related to brain issues, they do not specifically describe the loss of consciousness resulting from a blow to the head in the same way that a concussion does.

A CVA refers to a stroke, a contusion typically indicates bruising of the brain tissue itself, while a TIA is a temporary period of symptoms similar to those of a stroke. Thus, in the context of the options provided and the effect of a blow to the skull, "concussion" is the most appropriate choice.
