The most compelling of these options is option D; that is because, unlike the other options, it specifically addresses hearing loss due to ear buds, plus it involves research done by a professional.
Hope this helps.

I believe it is D.
Hearing loss could be from a number of things, and is not only in the U.S. Mentioning his father's hearing loss may not be too persuasive because its not from headphones, and because its from old age. It also won't be persuasive because that is only one case of hearing loss. Concerts are irrelevant to the argument.
It is D because the author is quoting someone who had done research and had hard evidence.
