Answer:
The correct verb phrase to complete the sentence is option A, "vamos a visitar", which means "we are going to visit".
Step-by-step explanation:
The sentence "Mañana mis padres y yo __________ algunas universidades" translates to "Tomorrow my parents and I are going to visit some universities." The subject of the sentence is "mis padres y yo" (my parents and I), which is plural, and the verb needs to agree with the subject in both number and person. In this case, the correct verb phrase is "vamos a visitar", which is the first person plural (we) conjugation of the verb "visitar" (to visit) in the present tense along with the future tense marker "vamos a" (going to).
