Okay so its basically asking you how it happened... well here it is:
Fueron al parque sin una correa para el gato, luego el gato se escapó y salió a la carretera y venía un automóvil, así que para evitar al gato, el automóvil chocó contra un árbol. El gato se asustó y subió al árbol. Ahora el gato está atrapado.
In english:
They went to the park without a leash for the cat, then the cat got away and on the road and a car was coming, so to avoid the cat the car ran into a tree. The cat got scared and went up the tree. Now the cat is stuck.
I believe that the answer is B though you weren’t that specific,but I hope this helps .
