multiple-choice question
what is the reason for using ser?
occupation
description
characteristic

Explanation:

In Spanish grammar, the verb "ser" is used for permanent or inherent traits. "Guapa" (beautiful) describes an inherent characteristic of a person. Occupations use "ser" too, but the visual context points to a descriptive characteristic. Description is a broader term, but characteristic is the specific reason here for this adjective use.

Answer:

characteristic
