it is D, because it tells you to add something that would convince readers to volunteer for making a difference in someone life, like a soup kitchen.
Explanation:
Including a fact about how nursing homes are run would probably make it much more boring and the person isn't going to want to do it, Including an interview with someone who has never volunteered makes no sense so how will they know anything about it and convince the reader to volunteer? Including an image of a YMCA building wouldn't convince the reader to volunteer, cause it tells them nothing, all they will be thinking is, "okay? its a building what about it?" a picture of a building is not that interesting so it wouldn't convince them of anything, much less care about the cause.
so therefore it is D. include a quote from someone who has volunteered
