which is the best place to find evidence for an argumentative essay?\na novel\na blog\na primary source\na…

Brief Explanations:

A novel is a work of fiction, so it's not reliable for factual evidence. A blog often contains personal opinions and may lack credibility. A biased source presents information with a slant, so it's not objective. A primary source (like original documents, research, etc.) provides direct, authentic information, making it the best for evidence in an argumentative essay.
