Question

Choose the correct form of the adjective to describe the following noun.

Answer 1

Answer:

felices

Explanation:

Los chicos felices

Translation:

Happy boys

First we discard "felizes" and "felizos" these words in Spanish do not exist. For the choice of "felices" the amount of the subject is taken into account, in this case to refer to the boys is plural and as in Spanish the adjectives are pluralized, the plural of "feliz" (singular) is "felices"

Answer 2

The actual answer is felices
