Um.... I think this website is a credible source to use for research.... you can get information you might not even find online! But if there is a reason this is not a credible research source, it's:
1. People can give out false information- people can give out information they think that is not but it's actually not.
(I'm sorry, Brainly members for sayng that!)
Other than that, I don't think Brainly isn't a credible source. It is a great web that everyone helps one another and in my opinion, I think this sort of helps refresh everyone's brain of what they learn before.
The answer is A. If they are selling a product, their opinion will be biased as they are trying to get money and sell rather than using credible facts.
