उत्तर
Perfectly elastic demand curve is horizontal to OX axis.
Explanation:
Demand for a good is said to be perfectly elastic when the demand is infinitely responsive to changes in price. In other words, even a small change in price brings about a large change in demand. Such a demand curve is a horizontal straight line parallel to x-axis.
