Answer: Option E
Step-by-step explanation: Elasticity refers to the tendency of a good or service of changing its demand with respect to change in its price. Higher elasticity means higher change and vice versa. The elasticity is dependent on a number of factors including the proportion of income that the consumer uses for a commodity.
A rational consumer will not take into consideration change in price if the portion of his income he spends on such commodity is low.
Hence from the above we can conclude that the correct option is E.
