Answer:
The correct answer is 3). Soy Susana. Voy al jardín con mi papá y Lorenzo.
Explanation:
Soy Susana. Voy al jardín con mi papá y Lorenzo. This means: I'm Susana. I go to the garden with my father and Lorenzo. Jardín is a masculine noun, that's why all the options that have "a la" are incorrect, because they are referring to a female noun. Option 1) has "al", which would be correct but the verb isn't conjugated in the first person as it should be. "Vas" is in the second person of the singular.
