Step-by-step explanation:
The correct answer to this question is a) Signal, Pass.
When you want to pass a bicycle on a narrow traffic lane when an oncoming car is approaching, it is important to signal your intention to pass. This lets both the bicyclist and the oncoming car know what you are planning to do. You can do this by using your vehicle's turn signal.
Once you have signaled, you can proceed to pass the bicycle. However, always make sure to leave enough space between your vehicle and the bicycle and wait for a safe opportunity to pass.
