Explanation:

Price elasticity of demand indicates how the changes in the price of a commodity affect its demand. Price elasticity is a measure of how the demand for a good or responds to changes in prices. Goods or service is said to be price elastic if a small change in price has a substantial effect on the quantities demanded.

A product is price-inelastic when a  change in prices does not have a big impact on its demand. in other words, the demand for that product is not affected by changes in price. Milk is price inelastic as people changes in its price has little effect on demand. People still need milk; a small change in price will not stop them from consuming it.
