Explanation:

To adjust a head restraint properly, the reference point is the ears. The top of the head restraint should align with the top of the ears (or slightly above) for safety, especially in vehicle safety to protect against whiplash. Eyes, neck, nose, or shoulders aren't the standard reference here.

Answer:

C. Your ears (Note: Assuming the options are labeled A - E as A. Your eyes, B. Your neck, C. Your ears, D. Your shoulders, E. Your nose)
