The correct answer is:
C. pagó, pagué
Explanation:
1. The sentence describes two different actions related to payment: "Yo pedí la cuenta por separado" (I asked for the bill separately) and "Yo con la tarjeta y él con dinero en efectivo" (I with the card and he with cash).
2. Since the subject "Yo" (I) is mentioned twice in the sentence, the first action of paying should correspond to "Yo" (I). This aligns with the verb "pagué" which means "I paid" in Spanish.
3. The second action of paying, related to "él" (he), should be conjugated as "pagó" which means "he paid" in Spanish.
4. Therefore, the correct verb pair to complete the sentence is "Yo pagué" (I paid), and "él pagó" (he paid).
