Critical Reasoning

The news media is often accused of being willing to do anything for ratings. However, recent action by a television network indicates that the news media is sometimes guided by moral principle. This network had discovered through polling voters on the east coast that the Republican candidate for President had garnered enough votes to ensure victory before the polls closed on the west coast. However, the network withheld this information until the polls on the west coast closed so that the information would not affect the outcome of key congressional races.
Which one of the following most strengthens the argument?
(A) The network had endorsed the Republican candidate for President.
(B) The network expected its ratings to increase if it predicted the winner of the presidential race, and to decrease if did not predict the winner.
(C) A rival network did predict a winner of the presidential race before the polls on the west coast closed.
(D) The network believed that it would receive higher ratings by not predicting the winner of the presidential race.
(E) The network feared that predicting the winner of the presidential race could so anger Congress that it might enact legislation preventing all future polling outside of voting centers.
