How would most spanish speakers ask an elderly person how he/she is doing? a. ? cómo estás? b. hasta pronto. c. ? cómo te va? d. ? cómo le va?

It is D. Cómo le va?

in Spanish when you speak to an elderly person you speak as if it was 3rd person.

the translation of Cómo le va? is :how is it going? but said as if you were talking in 3rd person. If you talk in 2nd person it would be Cómo te va?

i have to listen to the audio to be able to answer your question.

cuando era un niño durante el verano salía a jugar con mis mejores amigos, ¿verdad?
