The quotes for the question are:
A. “Any story I can write linking a powerful politician to a Hollywood celebrity doubles the clicks to our site.”
B. “Robbins doesn’t have a shot at winning and isn’t worth covering, but my editor says we have to make him look electable.”
C. “Safety and security will never be as important as freedom of speech, and I hope every article I write reflects that.”
D. “My story will be about the workers losing their jobs, since this is the most pressing problem facing out community.”
Thus the correct answer is B.
The question asks for how bias in media is created by the superiors of the journalists. The only option with this type of situation is B when a journalist is talking about how someone clearly isn't a strong candidate but his/her superior, the editor gives an order to represent him electable.
