If someone ahead of you is driving too slowly:

Answer: D — Signal and pass on the right with care

Tailgating and honking your horn can be aggressive and potentially dangerous behaviors, and should be avoided. Passing on the left is typically done for faster moving traffic and could be unsafe if the slower driver suddenly changes lanes. Passing on the right is generally not the preferred option, but if you ensure you are following traffic laws and signals, it is the safest choice in this situation. Remember to always drive defensively and with caution.
