Correct Answer: Neither price axis , nor quantity axis.

Solution : The correct option is Neither price axis, nor quantity axis.

The price (vertical axis) or quantity (horizontal axis) axis will never be touched by a unit price elastic demand curve during its entire length. This implies that if a good or service's price goes up by a particular percentage, the quantity desired will drop by precisely that same amount, resulting in no change in consumers' overall spending. On the other hand, if the price drops by a given amount, the quantity required will go up by the same amount.
