Justification for the correct and incorrect answer:
A.
Equilibrium Price: This option is incorrect.
It is the price determined by the supply and demand of a good. The interaction at which demand and supply of a particularly good meet, that point is known as equilibrium price. As it only determines the price of the good, it is not the correct measure of the economic indicator.
B.
Consumer Price Index: This option is correct.
It shows how the price changes in a particular period. It is helpful in the prediction of the future trends of a particular good. It is the correct indicator of measuring the economy.
C.
Job Satisfaction Rate: This option is incorrect.
This rate shows how people feel satisfied, self-motivated, and happy with their jobs. It doesn’t have any numerical value. It is related to the economy, but it cannot be quantified. Therefore, it is not the correct measure of the economic indicator.
D.
Presidential Approval Rate: This option is incorrect.
It is the rate of polling the opinion for a particular program or in favor of a person. The economy is not defined by the polling method because it is uncertain and follows uncertain trend. So, it is not a correct measure of the economic indicator.
