Answer:
A.
Explanation:
The answer is A because the weight of the crate is sitting on something rough. The roughness is going to resist anything that tries to move against it because the force being exerted by the 2 workers is not strong enough to get the crate to move out of its place on the mud since it's static.
The answer can't be B because ice is smooth and doesn't have any friction, the little girl can't move it because it's to heavy for her to move, not because there's friction acting against it.
Answer:
A. A heavy crate standing on a rough patch of mud and is being pushed by two workers, but they cannot get it to move.
