C)Yes.Correct
# Explanation
**Yes, you must yield.** Vehicles on emergency service (ambulances, firefighters, police) have absolute priority over any other vehicle, even if you are at an intersection where you have right of way. They are exempt from complying with traffic rules when acting in an emergency, so you must yield to them immediately to facilitate their movement.
