The answer to this is C. You have the right to pass by the vehicle especially if the vehicle does not seem to show any sign of moving again. Even if the sudden stop may have frustrated you, you need to keep your cool while on the road. You still need to check if there are pedestrians because they may become affected if you allow your hot temper to take over.
Passing the vehicle without checking your surroundings may lead to an accident and you do not want that. Letter D is not ideal especially if you are passing through a honk-free zone. It can also just annoy the other cars that are not affected by your present situation.
