Question

Responde en español. ¿Me invitas?
A. Sí, me invitas.
B. Sí, te invito.
C. Sí, te invitas.
D. Sí, me invito.

Answer 1

This would have to be B. Sí, te invito. (Yes, I'll invite you.)

Answer 2

¿Me invitas? - Am I invited?
B. Sí, te invito is the answer.

Both A. and C. is not only in second-person singular form but another way to help you eliminate wrong answers is making sure the question and the answer aren't in the same form, which in this case was invitas. D. on the other hand as well as A. say invited me, instead of I invited you making it wrong as well.
