Answer: can be proven to be true
Explanation:
a fact must be completely unbiased yet able to proven
if something reflects the feelings and ideas of the author it is an opinion
if something has no proof, it simply must be accepted can be many things but could be compared to a nation such as faith
i honestly have no idea why d is an option, but i can’t see any way it is relevant to facts other than that people want to see the proof that it is a fact
hope this helps :)
