You can legally park your vehicle:
Answer: B — At a red curb
Parking on the shoulder of a freeway is illegal and can be dangerous as it could potentially block traffic. Parking at a red curb also is illegal as it is usually reserved for emergency vehicles. Parking at a yellow curb is typically reserved for loading and unloading, so it is not a legal option for parking. Therefore, none of the other options are correct and B is the only legal choice for parking your vehicle.
