FIGURE 4-3
-Refer to Figure 4-3.The diagram shows a rightward shift in the demand curve for some good,and the short-run and long-run supply curves (S_S and S_L,respectively) .In the new short-run equilibrium after the increase in demand,producers' revenue

A) is unambiguously lower than in the long-run equilibrium at E_L.
B) could be higher or lower than at E₀,depending on the short-run elasticity of supply.
C) is unambiguously higher than at E₀.
D) is unambiguously lower than at E₀.
E) is unambiguously higher than at E_L.
