Need help urgently with Spanish homework

It’s almost lunchtime and an exchange student from paraguay is asking for directions to the cafeteria. give them directions (using the phrases you learned in the tutorial) from your spanish class to the cafeteria. make sure that you include at least 4 commands that you learned in this unit, and if you need to, be creative with the route they will take (we won’t call your principal to verify). remember, the main goal is to practice directions vocabulary!

Yo en la biblioteca hasta las cinco de la tarde. a. estarás b. estará c. estaré d. estarán

This is very confusing, can someone me? picture above!
