The graph shows excess demand. A graph titled Excess supply has quantity on the x-axis and price on the y-axis. A line with positive slope represents supply and a line with negative slope represents demand. The lines intersect at the point of equilibrium (p star, Q star). A point on the demand line is (P 2, quantity demanded) and a point on the supply line is (P 2, quantity supplied). Both points are lower than the point of equilibrium. Excess demand is indicated between the 2 points.

Which needs to happen in order to stop disequilibrium from occurring?

a) Q needs to be coordinated with supply.
b) Q needs to be coordinated with demand.
c) The price of goods needs to be increased.
d) The price of goods needs to be decreased.
