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.
gracias que tengas un buen día(thank you have a nice day) is in my opinion the most common phrase and easiest to learn to a non-speaking spanish person.
D is your best answer choice, because Madrid is located ~the middle of Spain. The only answer choice towards the middle is d, therefore making it your answer.
