The correct answer is:
c. bebías
Explanation:
- The sentence "Yo siempre bebías jugo de naranja con el desayuno" means "I always used to drink orange juice with breakfast."
- The verb "bebías" is in the imperfect tense in Spanish, which indicates a habitual or repeated action in the past.
- The subject "Yo" (I) matches with the verb conjugation "bebías" to maintain agreement in person and number.
