Choose the correct word to complete the wizard's inventory check.

"How many invisibility potions do we have left in stock?" "I'm afraid we have _____."

The correct answer is none.

None is a pronoun that means "zero." We use it by itself when the noun (invisibility potions) is already understood. We cannot use "no" here because "no" must always be followed directly by a noun (e.g., "we have no potions").
