watching for different types of signs or symptoms after a student gets a hit to the head or body.
wait for an student to report that they may have a concussion.

Explanation:

Concussions are often identified by observing signs and symptoms (like headache, confusion, dizziness) after a head or body hit. CT/MRI scans (option A) may not always show concussions as they are functional (not structural) brain injuries. Waiting for self - report (option C) is not reliable as some may downplay or not recognize symptoms.

Answer:

B. Watching for different types of signs or symptoms after a student gets a hit to the head or body.
