[D] Demand changes infinitely
Show Answer
Correct Answer: A [Demand doesn’t change with price]

Price elasticity < 1, less than unit elastic- % change in demand is less than that in price
Price elasticity = 1, Unit elastic – % change in demand is equal that in price
Price elasticity > 1, more than unit elastic – % change in demand is more than that in price
Price elasticity = ∞ , Perfectly elastic Demand changes infinitely
