Answer:
The revision which best reduces the wordiness in the sentence without changing its overall meaning is the following one:
C.Researchers found that banning cell phone use while driving is associated with a lower accident rate in urban areas.
Explanation:
It reduces the wordiness, since it removes unnecessary words and keeps the overall meaning. Check it out:
Researchers found that banning drivers from cell phone use while driving is associated with a lower accident rate in urban areas.
If we are talking about cell phone use while driving, it is obvious that drivers are the ones who should be banned from it. Therefore, the words in bold can be dropped for their redundancy.
