What is the ultimate goal of satire? to make the audience laugh to illuminate an important issue to offer a suggestion for improvement to place blame on a specific person

Here, have a helpful copy-paste: the use of irony, sarcasm, ridicule, or the like, in exposing, denouncing, or deriding vice, folly, etc. So I believe that the answer your looking for is to illuminate an important issue in a usually humorous fashion, hope this helps

It’s the first one.
