Final answer:

The correct statement is: i. If a percentage change in price results in a greater percentage change in quantity demanded, then demand is elastic.

Step-by-step explanation:

The correct statement is: i. If a percentage change in price results in a greater percentage change in quantity demanded, then demand is elastic. Price elasticity of demand measures how responsive quantity demanded is to a change in price. If a small change in price leads to a relatively large change in quantity demanded, then demand is considered elastic.

For example, let's say the price of a product decreases by 10% and as a result, the quantity demanded increases by 15%. In this case, the percentage change in quantity demanded (15%) is greater than the percentage change in price (10%), indicating elastic demand.
