Answer:
D) a rise in price
Explanation:
At the equilibrium point, the quantity demanded and the quantity supplied are the same. There is no excess shortage or supply in both demand and supply.
A shortage occurs when suppliers are not able to meet the market demand. Here, demand is the quantity that buyers are willing to buys at a specific price over time. As per the law of demand, high product price causes demand to decrease while low price results in increased demand.
A shortage of a product means its demand is high. Many buyers are willing to buy the commodity at the current price. As per the law of demand, a price increase will result in reduced demand and achieve equilibrium.
