The correct verb to complete the sentence is:
a. comíamos
Explanation:
1. The sentence states, "Mi familia y yo ____ la cena todos los días a las seis."
2. To correctly complete the sentence in the imperfect tense (used for ongoing or repeated actions in the past), we need the verb "comer" conjugated to match the subject "Mi familia y yo."
3. The correct imperfect form of "comer" for "Mi familia y yo" is "comíamos," which means "we used to eat."
4. Therefore, the complete sentence would be: "Mi familia y yo comíamos la cena todos los días a las seis."
