Respuesta :

A. Enseña, and the symbol on top of the n is called a tilde.

Right answer:

a. enseña

Enseña is the more logical answer because it comes from the verb enseñar (to teach). So enseña is the conjugation of this verb for the third person singular in the simple present tense. The simple present tense is used to talk about habitual actions or routines. So Miguel is a math teacher. Finally:

Miguel enseña matematicas (Miguel teaches math)
