Answer
Brief Explanations:
The verb "pagaba" is in the imperfect tense in Spanish, which is used for actions that were habitual or ongoing in the past. "De vez en cuando" (from time to time) fits with the imperfect tense as it describes a habitual action. "El mes pasado" (last month), "Anoche" (last night), and "Hoy" (today) are more associated with preterite tense (completed actions) rather than imperfect for habitual actions.
Answer:
C. De vez en cuando
