A.The case of an "increase in demand" and a simultaneous "decrease in supply" where, with no additional information information, the direction of change in the equilibrium quantity is ambiguous.


B. The case of an "increase in demand" and a simultaneous "decrease in supply" where, with no additional information, the direction of change in the equilibrium quantity is unambiguous.


C. The case of an "decrease in demand" and a simultaneous "increase in supply" where, with no additional information information, the direction of change in the equilibrium quantity is ambiguous.

D. The case of an "decrease in demand" and a simultaneous "increase in supply" where, with no additional information information, the direction of change in the equilibrium quantity is unambiguous.
