Answer:
A. While driving to work this morning, I passed a car accident at the corner of Elm and Juniper.
Step-by-step explanation:
This is the sentence that is most clearly written. In this sentence, we learn everything that is relevant to the situation. We are told the event, the moment it happened, and the location. Moreover, the sentence introduces the setting (time and place) from the beginning, which allows the reader to locate himself in the story. Finally, the sentence is written in active voice, which contributes to its clarity as the subject of the sentence and the action are clear.
