Remember to properly conjugate the verbs in spanish, for the verb Salir, in present, we have different ways to conjugate the verb depending on who is performing the action:
Yo salgo
Tú sales
Él/ella salen
Ellos salen
Nosotros salimos
In the sentence it says Yo, since Yo is the subject that is performing the action, we will use "Salgo", and that is the correct option.
