Answer :
Answer:
The correct answer is option a.
Explanation:
The word 'demand' in economics refers to a schedule of the quantity of a product that buyers would be willing to buy and able to afford at alternative prices in a given period of time.
The market demand is the sum of all the individual consumer demands. The demand and price are inversely related. So an increase in price will cause the demand to decrease and vice versa while other factors remain constant.
