Answer:
B. parked
Explanation:
In the sentence, there are two verbs “parked” and “waited.” “Parked” is an intransitive verb because it is a verb that can take an object (in this case, it takes the object “car”), while “waited” is an intransitive verb because it is a verb that does not need an object in order to express action, nor in this sentence or in any other sentence, just like the verbs “arrive” and “joke,” for example.
