Question

when approaching a bicyclist from the rear, you should slow down and
select a letter to choose your answer.
a tap your horn to warn the bicyclist.
b follow the bicyclist closely until they signal it is safe to pass.
c wait until it is safe to pass the bicyclist with at least three feet of clearance.

Explanation:

Tapping a horn can startle a cyclist and cause an accident, so option A is unsafe. Following closely (option B) is dangerous as it leaves no reaction time for sudden stops or maneuvers. The safest practice is to wait for a clear opportunity to pass with enough space (at least 3 feet) to avoid endangering the cyclist.

Answer:

C. Wait until it is safe to pass the bicyclist with at least three feet of clearance.
