A woman is straining to lift a large crate, without success because it is too heavy

We denote the forces on the crate as follows: P is the upward force the woman exerts on the crate, C is the vertical contact force exerted on the crate by the floor, and W is the weight of the crate. How are the magnitudes of these forces related while the woman is trying unsuccessfully to lift the crate? A) P + C = W
B) P + C < W
C) P + C > W
D) P = C
