The correct answer would be C. Soy
Yo soy Mexicano.
I am Mexican.
A would be wrong since eres is are and I are Mexican wouldn’t make sense. Tú eres Mexicano would make sense.
B is also wrong since estás means are you. For example:¿ estás en Camino? Are you on your way? Therefore B is wrong
D is also wrong since estoy is in the yo form but it is used incorrectly. An example sentence of this would be: Estoy en Camino. I am on my way. Estoy means I am.
This leaves C as the correct answer since soy mean am. You soy Mexicano is correct.
Hope this helps! :3
