Answer:
The best way to revise the sentence is the one expressed in letter D. a concern of the townspeople.
Explanation:
First, let's ask this question to the sentence: <u>What was the concern of the townspeople? That there would be an excess of traffic noise. This information is given immediately before we learn that the townspeople were concerned about it. Thus, we can transform the last clause, "this was a concern of the townspeople," into an appositive. By doing so, we connect the last clause to the rest of the sentence in a simpler yet effective manner. It's as if we are simply adding an extra information to what we already know</u>:
By routing the new highway around the town instead of through the middle of it, the governor prevented an excess of traffic noise, a concern of the townspeople.

Hello! 
I unfortunately cannot answer multiple questions in one answer, but what I can tell you, is the difference between a complete sentence and a fragment taken from one.  A complete sentence would be "When Catherine rode her bike to the store, she bought ice cream and cookies."  
A fragment is taken from a complete sentence, and it looks like this.
"When Catherine rode her bike to the store."
Hope I helped!
Have a wonderful day!  :)
