Answer 1

Bonjour !

How would you say goodbye to a friend you might not see again for a long time?

C.

Au revoir! À bientôt!

Answer 2

The answer is C. Au revoir! À bientôt! This is because the sentence "à bientôt "means "see you soon." This is more suited to the occasion than "à plus tard", which means "see you later", and "à demain", which means "see you tomorrow", as well as just plain "au revoir", which means goodbye.
