The correct ending for -ER/-IR verbs in the imperfect tense in Spanish is:

ía, ías, ía, íamos, íais, ían

This is the third option provided in your list. The imperfect tense is used to describe ongoing or habitual actions in the past, and it is conjugated differently for -AR verbs (using the first set of endings, "aba, abas, aba, ábamos, abais, aban") and for -ER/-IR verbs (using "ía, ías, ía, íamos, íais, ían").

The second and fourth options ("é, aste, ó, amos, asteis, aron" and "í, iste, ió, imos, isteis, ieron") are the conjugations for the preterite tense, which is used for actions that were completed in the past, and are not used for the imperfect tense. The second set is for -AR verbs in the preterite, and the fourth set is for -ER and -IR verbs in the preterite.
