Answer:
I love to listen to jazz music, while my sister only likes pop music. And we share the same bedroom. We decided to switch off music every day; and it's working great!
The answer should be B) because social media is a long distance communication tool for people, so not C) since that's false, that's where most danger is at is online, not D) because that wasn't the original purpose, but sadly its become popular now and not A) because that's incorrect.
Is that the correct question?
