The correct answer would be: Estés
Your mother expects you to be home by 8.
Tú madre espera que tú estés en class a las ocho.
Estés in the infinitive form is estar which has an -ar ending. Due to this you can change it to -es when you are using “tú”.
Tú means you. Due to this you must change the infinitive form (-ar) to -és. Which is why it is estés since they are talking about ‘you’ in the sentence.
