Answer:
Nosotros comíamos pasta.
Step-by-step explanation:
The correct conjugation is: Nosotros comíamos pasta. In English this would be: we used to eat pasta. The options "comí" and "comió" are incorrect because they are not in the third person of the plural. The option "comábamos" is incorrect as it's not an actual Spanish word. It doesn't exist.
The conjugation of the verb comer in the imperfect would be:
yo comía
tú comías
él o ella comía
nosotros comíamos
vosotros o ustedes comían
ellos comían
