Explanation:

When a student returns to sports prematurely during concussion recovery:

• Physiologically, the brain needs time to heal. Physical activity can disrupt the healing process, leading to a prolonged recovery period (explanation for "Take longer for the student to feel better").
• Biomechanically, a still - recovering brain is more vulnerable. The physical impacts and movements in sports can put the student at a higher risk of more severe brain injuries like second - impact syndrome (explanation for "Put the student at risk for more serious injury").

Answer:

C. Both A and B.
