Answer: I think C, D, A would be the most reasonable answers to this question, but feel free to disagree.
Explanation: Here's how I used the process of elimination to find your answers.
A. Printed media is everywhere, although technology has become more popular. I'd say that this is an advantage, as the info on the media will be spread to many people.
B. Print media does cost a lot to produce when it comes to money and its effects on the environment. This is not an advantage to me.
C. People can definitely get (retain) printed media and read as much as they'd like. This would likely help with increasing the effectiveness of its message(s), so this is an advantage.
D. Print media is arguably not as fast as, say, a text message or email. This is not much of an advantage to me.
I hope that my answer(s) help you out somehow! :)
