Answer:
C
Step-by-step explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
If the demand for a newly released novel is less price-elastic than the demand for an older novel, it means that the demand for the new novel is less price sensitive when compared to the older novel.
A price discriminating firm would sell the new novel at a higher price than the older novel because demand is less sensitive to price. As a result, total revenue would increase.
