It's a great idea to research Facebook's Community Standards before the interview, so you're well-versed on this topic. When you answer, highlight your knowledge of the standards and focus on the ones you think are most important. Avoid criticizing any standards, though it is okay to make positive suggestions about how to improve them.

"Facebook's Community Standards are very thorough, and overall I think they do an excellent job of protecting users from harmful content. I'm especially impressed with how many standards are related to protecting minors and preventing Facebook for being used for violence. Because cyberbullying has become increasingly common, I'd love to be part of any initiatives focused on developing new policies to prevent it."
