The correct answers are: There are no truffles left in the pantry! There aren't any truffles left in the pantry! None of the truffles are left in the pantry!

No is a determiner and goes directly before a noun (no truffles).

Any is used in negative sentences with "not" (aren't any truffles).

None is a pronoun. When followed by a specific noun, we must use "none of the..." (none of the truffles).

"None truffles" is incorrect because "none" cannot be used directly as an adjective/determiner before a noun.

"Aren't no truffles" is a double negative, which is grammatically incorrect in Standard English.
