The diagram represents a sphere under water. P, Q, R and S are forces acting on the sphere due to the pressure of the water. Each force acts perpendicularly to the sphere's surface. P and R act in opposite directions vertically. Q and S act in opposite directions horizontally. Which information about the magnitudes of the forces is correct?

1. AP < R and S = Q
2. BP > R and S = Q
3. CP = R and S = Q and P < S
4. DP = R and S = Q and P = S
