Answer:
D. Head injuries
Step-by-step explanation:
Athletes who participate in contact sports, such as football, are more likely to experience head injuries. This is primarily due to the nature of contact sports, which involve physical collisions and impacts. Head injuries can range from concussions to more severe traumatic brain injuries. The high impact and force involved in contact sports increase the risk of head injuries, especially if proper safety precautions are not taken or if the rules and regulations of the sport are not followed. The frequency and severity of head injuries in contact sports have led to increased awareness and efforts to improve player safety.
