Answer:
facts and evidence
Explanation:
An argument, in critical and logical thinking or in philosophical terms, is list of statements or premises leading to the conclusion of the point or claim asserted. An argument involves evidence and facts to support or back up the claims stated.
Argument usually involves two or more people. Claiming a statement and providing vague information about the same makes an argument weak. It can not be backed up with just assumptions but facts to make your point or opinion much stronger.
Facts are the premises in an argument that are considered to be true.
Evidence, on the other hand, proves that the facts provided are true and valid.
So, the correct option is second: 'Facts and evidence.'
