Agree With/ To?

Hi there!

When you read an article in a newspaper and think things written in the article are right, which do you say?

a) I agree with this article.
b) I agree with the writer.
c) I agree to this article.
d) I agree to the writer.

If there are any other appropriate ways in a situation like this, I would like to know them too.

Thank you for youe help.

I always enjoy this website.
