how the amount of a good changes when its price goes up or down

Explanation:

In economics, elasticity is a core concept that quantifies the responsiveness of one variable to changes in another. The most common form is price elasticity, which specifically measures how the quantity demanded or supplied of a good shifts in response to a change in the good's own price. The other options describe changes from production inputs, distribution, or labor, which are not related to the definition of elasticity.

Answer:

how the amount of a good changes when its price goes up or down
