The best answer here is D. Each type of broadcast is going to offer something different. While hearing a radio broadcast might seem to not convey the depth of the disaster, a video one will show how terrible it is. Usually this will make the audience more aware of the reality. The same is true to a transcript. Going back to read something that has already happened takes something from the presentation. You don't get the emotion that would be present in a radio broadcast or even a video one.
