Le pedí asiento al lado de la ventanilla porque quiero ver la cuidad de Ponce por la noche.
Why?
A) de la salida is by the exit, he wants to see the city so why would he be by the exit?
B) del pasillo, what's the good in sitting by the hallway if you wanna see the city?
C) del turista, why would you sit by a tourist to look at the city?
This is how we know D) de la ventanilla is correct, because it's a window and you look out windows to see the outside.
Hope this helps!~
