The word "comía" is in the imperfect tense. In Spanish, the imperfect tense is used to describe past actions that were ongoing or habitual. It is often used to provide background information or to set the scene in a narrative. In this case, "comía" indicates that someone was eating in the past, but it doesn't specify when or for how long. The other tenses listed (present, preterite, future, conditional) do not match the given word "comía," so the correct answer is imperfect.
