Answer:
The right answer is, C. Tener que.
Explanation:
Because when we speak in the first person and we are going to carry out some activity or commitment, to report that we have something to do we use the expression "Tengo que".
example, I have to do the dishes before going to play.
* Tengo que lavar los platos antes de ir a jugar.
Los profesionales les pagan por jugar, y a los aficionados no
If something seems temporary, use estar, if it is more permanent quality, use ser. When you are thinking about whether to use ser or estar, consider which question the verb “to be” is answering. If you want to talk about ‘where’ something is, use estar.
