Final answer:
The demand for a good is elastic when the percentage change in price results in a smaller percentage change in quantity demanded.
Step-by-step explanation:
The correct answer is i. percentage change in price will result in a smaller percentage change in quantity demanded.
When the demand for a good is elastic, it means that a small change in price will lead to a relatively larger change in quantity demanded. In other words, the percentage change in quantity demanded is greater than the percentage change in price.
For example, if the price of a product decreases by 10%, the quantity demanded may increase by 20%. On the other hand, if the price increases by 10%, the quantity demanded may decrease by 20%. This indicates a relatively higher sensitivity of demand to price changes, resulting in a smaller percentage change in quantity demanded compared to the percentage change in price.
