hay que comer naranjas means we have to eat oranges

On the other hand, from C) tienen is the conjugation of the verb tener for the third person plural in the simple present. Finally, from D) tienes is the conjugation of the verb tener for the second person singular in the simple present.
3. Right answer:
A) correct
First of all, tenemos is the conjugation of the verb tener for the first person plural in the simple present. On the other hand, vivir is an infinitive verb that means to live.
