¿Te gusta el maestro? = do you like the teacher?
So sense you didn't give me any answers I would say
Sí, ella/<span>él</span> es muy agradable. = Yes, she/he is very nice.
Mrs Vargas, please is the answer
Estamos: we are
estas: you are
estan: they are
The question says where are Maria and Adela? You should change “Maria and Adela” to they, do the third option is correct.
