Question

20/30
los chicos ____ (vestirse) rápidamente.
vesten
se vesten
visten
se visten

Explanation:

The sentence uses the reflexive verb vestirse (to get dressed) with the plural subject Los chicos (the boys). For plural third-person subjects, the reflexive verb conjugates to se visten: the reflexive pronoun se matches the plural subject, and the verb stem vest- takes the plural third-person ending -en.

Answer:

se visten
