Choose the correct word to complete the travelers' frantic airport conversation about forgotten items.

"Did you pack any sunscreen in the checked bag?" asked Leo.

"I have no idea what you're talking about," replied Mia.

"Great, so out of three expensive bottles, we brought exactly none!" Leo groaned.

"Did you pack any sunscreen in the checked bag?" asked Leo.

We typically use any in questions to ask about the existence or quantity of something.

"I have no idea what you're talking about," replied Mia.

No is used directly before a noun ("idea") to mean "zero" or "not any."

"Great, so out of three expensive bottles, we brought exactly none!" Leo groaned.

None is a pronoun that replaces the noun ("sunscreen/bottles"). It is used here because there is no noun immediately following it.
