But does anyone actually wear a helmet when they 🚴‍♂️
The correct answer is prevention.
The correct answer is "prevention." Wearing a helmet to avoid possible head injury is a preventive measure, as it helps reduce the risk of a head injury in case of an accident or fall. To arrive at this answer, I evaluated each option and determined that the most appropriate one is "prevention," as it directly correlates with the act of wearing a helmet to prevent a head injury.
