Both of these changes happen simultaneously in a market: the supply of good X falls and the demand for good X rises. This will result in: a. an increase in both the equilibrium price and quantity in the market.
b. an increase in the equilibrium quantity and an uncertain impact on the equilibrium price
c. a decrease in both the equilibrium price and quantity in the market.
d. an increase in the equilibrium price and an uncertain impact on the equilibrium quantity.

d.

Explanation:

This scenario will result in an increase in the equilibrium price and an uncertain impact on the equilibrium quantity. This is because when customers in a market want a product but there is very little supply exists it makes the product more valuable and thus increases the price since consumers are willing to pay more for that product to get their hands on it. Scarcity increases price always, but while the supply and demand of a product are not the same this causes an uncertain impact on the equilibrium quantity.
