Question

tú ________ a tus abuelos el proximo verano cuando estemos de viaje.
opciones: cuidara, cuidar, cuidaras, cuidarás

Explanation:

The sentence refers to a future action ("el próximo verano" = next summer) with the subject "tú" (informal singular you). The correct conjugated form of the verb cuidar (to take care of) for future simple tense with "tú" is the accented form, as Spanish requires the accent mark to maintain the correct stress and grammatical correctness.

Answer:

cuidarás
