Which of the following sentences uses the present perfect correctly?

The present perfect is formed with the present-tense form of haber plus a past participle. For nosotros, the correct form is hemos, and correr has the past participle corrido, so “Nosotros hemos corrido por la playa” is correct. “Corrimos” is the preterite, while “corriendo” is a gerund, not a past participle.
