c. The skull has not been penetrated but there is damage to the brain.

Answer 1

Strong blows to the brain-case portion of the skull can cause fractures, leading to bleeding and brain injury.

Step-by-step explanation:

A closed-head injury is characterized by damage to the brain without penetration of the skull. Strong blows to the brain-case portion of the skull can cause fractures, leading to bleeding and subsequent brain injury. The most common type of closed-head injury is a linear skull fracture, where fracture lines radiate from the point of impact. Other types of fractures include comminuted fractures, depressed fractures, and contrecoup fractures.
