Why Is Wikipedia Generally Not Considered a Credible Source for Journalists

Multiple Choice

Why is Wikipedia generally not considered a credible source for journalists?

A) It makes research too easy by acting as a one-stop research tool that does not challenge writers to be creative or "think outside the box."
B) It is a user-edited platform that anyone can access and amend without the veracity of their entry being fact-checked before publication.
C) Almost everyone has access to Wikipedia on demand, so there is no point in consuming news media if their only source is something to which people have ready access.
D) It is run by subversives who wish to eliminate every other informative source available.
