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.
1. La
2. Los
3. Las
4. El
You simply use the present tense of the verb "haber" followed by the past participle of the main verb. Ex Siempre he preferido montar en bici que a caballo. Preferir is a stem-changing verb, but has regular past participle. .
