Which is an example of a conflict of interest? a reporter writes about a company he or she is currently suing. a reporter writes about a company that has just broken the law. a reporter writes about a team that just won the championship. a reporter writes about a politician who has just lost the election.

I would say the correct answer is A. a reporter writes about a company he or she is currently suing.
Because they are personally involved in the matter, it would be a conflict of interest to actually write about that particular company. This is because they may be biased and decide to write a negative review based solely on their personal opinions, when they should be objective as reporters.
