When an object is at rest on a horizontal surface, and nobody is pushing or pulling it, the frictional force acting on the object is zero. This is because the static friction force comes into play only when there is an attempt to move the object, but as there is no effort or force being applied to the crate, it remains still. Therefore, the correct answer is option A) zero.
