Answer :
The correct answer is B.
The other options are incorrect because the colons are unnecessary. They break up an otherwise complete sentence (i.e. Jessie's favorite sports are softball, volleyball, and field hockey.).
Option B is correct because without the colon, the sentence would not make sense (i.e. You ought to interview these people Mr. Ryan, Mrs. Komanowski, and Ms. Thayer).
