A Study Shows That People Who Watch the Local Evening

A study shows that people who watch the local evening news believe the world is more dangerous than people who do not watch the evening news. On the basis of this study, a newspaper reporter concludes that watching the evening news causes people to believe the world is more dangerous than it actually is. This is a flawed conclusion because

A) the reporter has a bias because he works for the newspaper.
B) it confuses a correlational relationship with a causal relationship.
C) it fails to compare evening news viewers with newspaper readers.
D) one study does not provide enough evidence to make this type of conclusion.
