The correct answer would be invalidated but the reasoning is quite subtle. Invalidated would implies the passport changes status from a valid one to an invalid one.

Nullify means to make into null, or nothing, a void. The passport still exists so cannot be said to have been nullified. One could nullify an action, such as nullifying a false vote, but we would not normally say we had nullified an object.
