b. objects outside the windows
Explanation
When detecting motion, the frame of reference is an important concept in physics. A frame of reference is a perspective from which motion is observed and measured. In this scenario, you are inside the bus, moving along with it. If you are using objects outside the bus (like trees and houses) to detect the motion, those objects are considered stationary relative to the Earth's surface. Since they provide a contrasting perspective against your motion, they act as an effective frame of reference.
