Answer:
C, Aboriginal languages are no longer spoken
Explanation:
Well, Australia actually does not have an official language, so that one is true. About 76% of Australians speak english, and about 2.5% of the citizens speak Mandarin Chinese. Aboriginal (Indigenous) languages will probably always be spoken. Even though there are only about 120 left of the original 250.
