Answer:
The correct answer is "Facts and opinions are not necessarily in opposition".
Step-by-step explanation:
A fact is a statement which can be proved because it is supported with data or any other means for verification. An opinion is a subjective statement that comes from someone's perspective. A fact and opinion are not necessarily in opposition, for instance, an opinion could be that the Earth is heavily contaminated, which is also a fact when a search on the data available supports this opinion.
