Concept:"I wish" is used to express a situation that is not true, so the verb that follows usually goes one tense back.
Explanation:When the wish refers to the present, we use the simple past form of the verb.
The verb "return" must therefore change from "returns" to "returned."
This does not mean the action happened in the past.
It simply shows that the action is hypothetical or unreal now.
The word "earlier" only tells us the time the driver should have come, but the wish is still an imagined present situation.
Among the options, only "returned" is the correct simple past form.
Answer:A. returned
