The height of the market demand curve at a certain quantity demanded represents the maximum price consumers are willing to pay for that quantity. If the statement about the height at a quantity of 16 being $5 is not true, it implies that the maximum price consumers are willing to pay for 16 units is not $5, which could be due to the aggregation of individual demands at a different price point.
