I believe the answer would be "slogans".
Let's begin with looking at the question. We know that this will be an <em>audio </em>message broadcasted to a <em>large </em>audience, so we need to keep these facts in mind when we look at the answer choices. Answer choice A, slogans, appears correct, because slogans are easy to remember especially for a large audience and can be broadcasted as an audio message. Next, answer choice B, appears incorrect, as images cannot be broadcasted via audio. Answer choice C, text, also cannot be broadcasted via audio. Last, although answer choice D is audio-based, it does not enhance the <em>message </em>of the PSA. Therefore, I believe the answer is A, Slogans.
