In Spanish, the imperfect tense for regular -ar verbs uses the ending -aba for the first-person singular. So for cantar, you take the stem cant- and add -aba to get cantaba. This form expresses a past action without a definite end or something that was habitual in the past. The other forms shown correspond to different subjects or to the preterite: cantabas is the tú form, cantábamos is the nosotros form, and cantaron is the they/you all form in the preterite. So cantaba is the correct choice for yo.
