a. está
b. están
c. es
d. son

1. el profesor

Explanation:

In Spanish, "estar" is used to express a temporary state like being sick. "Aarón" is a singular subject, so the correct form of "estar" is "está". "Estar" is conjugated as "están" for plural subjects, and "ser" (es/son) is used for more permanent characteristics or identities, not for a temporary illness state.

Answer:

a. está
