Answer :
(A)price must be above the equilibrium price. When demand for an item or service exceeds supply at the going rate, there is a shortage, which drives up the cost. Demand going up, everything else staying the same. will result in a rise in the equilibrium price.
In a market that is operating normally, the quantity provided and the quantity sought are in balance at a price determined by market forces. A shortage occurs when there is an imbalance between supply and demand for a good or service. The market is considered to be in a condition of disequilibrium when this happens. This circumstance often only lasts a short while before the product is supplied and the market returns to normal. It should be noted that the terms "shortage" and "scarcity" in economics should not be used interchangeably since while shortages are often transient and remediable, scarcities tend to be systemic and difficult to refill.
