The correct word from the list that best fits the sentence is "al". In Spanish, the preposition "al" is used to indicate movement towards a specific location. In this case, the sentence is talking about going "to the park" which translates to "al parque" in Spanish.
By selecting "al" from the list, the sentence would read: "Todos los días mis amigos y yo vamos al parque," meaning "Every day my friends and I go to the park."
This choice helps to accurately convey the intended meaning of the sentence in Spanish.
