D
I answered C and it was marked wrong
1. I think that the most popular conversation is about celebrities and relationships.
2. Parents have work and they have to take care of they're kids and they don't really have time.
3. I guess would be like whenever there is an event (not a fight) and when you are with friends. Also, if you want to celebrate an achievement. Basically on the weekend I guess.
4. Some people get cyberbullied and others get hacked.
The answer to your question is bad breath and drooling. Hope this helps! :)
