The word cocina in English is cooks so that makes it a verb
Con Permiso means with permission
Perdon means excuse me or my bad
Answer: Donde
Explanation:
Como means how.
Que means what.
The only appropriate answers are either donde or adonde. The reason it's not adonde, is because you use adonde when asking "to where" or "where to" if that makes sense. If you're simply asking where someone is, you say donde.
