a.decreases in the demand for computer memory have exceeded increases in supply.
b.decreases in the supply of computer memory have exceeded increases in demand.
c.increases in the demand for computer memory have exceeded increases in supply.
d.increases in the supply of computer memory have exceeded increases in demand.
