Answer:
En 2013, veías a tu padrino más.
Explanation:
Although the last two sentences are both in the imperfect tense, ver is the only irregular.
So the answer is (a) because in English the word is “paid” and (b) and (c) just don’t make sense the sentence states that “I (paid) the ring at the jewelry store.” I hope this helps!
A mis Padres no pueden hablar contigo.
