You are driving at night, and you see a bicyclist approaching from the opposite direction. you should
a. reduce your speed and flash your high beam headlights.
b. use your high beam headlights and reduce your speed.
c. slow down to a safe speed and avoid using your high beam headlights

The correct answer should be
c.slow down to a safe speed and avoid using your high beam headlights

High beam headlights should not be used because they can cause the person in the opposite direction to not see you because the light would bother them. If you are using them, you should lower them when approaching the cyclist since he can see your regular lights either way in the dark without it bothering him.
