Please add the rest of the question, so as I can answer it.
Go with a. I'm pretty sure it's already correct.
1. The best types of media would be new's papers" so that you can have a hard copy, and that the people who don't have access to technology can get to the resources." The next type would be a web page for those who can get access to the internet / technology. Finally, the last type would be like a book or a brochure so that someone who wants to know can take the information with them.
2. Some types of media that should not be included are some that are just people's opinions on the subject, because there is not any proven facts with their point of view.
3. Some examples that would be good are "history.com", any history website that is not made by a person that has just said random stuff about the topic, and some books about the extinction of the dinosaurs that you can find at a library.
Hope this helped you in any way!!!
