Answer

As θ increases, the static frictional force (fs) between the box and the ground decreases.

Work Step by Step

Static friction is only created when a force is pulling on a stationary object horizontally. As θ increases, the horizontal component of the force decreases. This effectively decreases the static friction between the box and the ground because the horizontal force is lessened.
