Question

which part of the sentence contains the reflexive verb?
tú te diviertes
tú
te diviertes
tus hermanos

Explanation:

Reflexive verbs in Spanish include a reflexive pronoun that matches the subject, paired with the conjugated verb. In "Tú te diviertes", "te" is the reflexive pronoun for the subject "tú", and "diviertes" is the conjugated reflexive verb form, so they function together as the reflexive verb phrase. The other options are either the subject ("tú") or an unrelated noun phrase ("tus hermanos").

Answer:

te diviertes
