Which of the following sentences uses the present perfect correctly?

The present perfect is formed with the present tense of haber plus a past participle. For nosotros, the correct form of haber is hemos, and the past participle of resolver is resuelto, so “Nosotros hemos resuelto comer menos” is correct. The other choices use either han, which goes with ellos/ellas/ustedes, or the incorrect participle “resolvido.”
