You didn't put all the alternatives, but I understand economics and I know exactly that concept.
Supply price elasticity measures how price changes impact the supply of goods and services. If the elasticity of supply is elastic, it means that supply is very sensitive to price changes. If the price goes down even slightly, the supply of goods will fall sharply. If the price increases, even if little, the offer will increase much. Conversely, if supply is inelastic, price changes will have little effect on supply for the good. If the price goes down, there will be little impact on the supply of the good. If the price increases, there will also be little impact on supply.
