Which pronoun correctly completes this conversation? juan: ¿conoces a la maestra de historia? eric: sí, yo conozco. la lo las los

The answer would be ellas (if they are both girls if not use ellos)    van a ( whereever they're going) for example: ellos/ ellas van a el cine

why dont you use a translator. just download the google translate app that allows you to gake a photo and then it translates everything for you.
