When demand is perfectly inelastic, it means that consumers will purchase the same quantity of a good regardless of price changes. This characteristic indicates that consumers view the product as a necessity, and their demand remains constant even when prices rise or fall significantly.

This behavior can be observed in essential goods, such as life-saving medications, where consumers are willing to pay any price because they need the product irrespective of its cost. The essence of perfect inelasticity is that there is no alternative or substitute that can fulfill the same need, leading to a situation where price fluctuations do not affect the quantity demanded at all.

As such, the correct understanding of how consumers respond in this scenario is that they will continue to purchase the same amount of the good no matter the price, underlining the idea that they will indeed pay any price necessary to secure the good.
