Demand is price inelastic for

Life saving medicines

The correct answer is option (4) : Life saving medicines

Demand is price inelastic for goods or services where consumers are less responsive to changes in price. This typically occurs for goods that are considered necessities, have limited substitutes, or where price forms a smaller part of the total cost. Demand for life-saving medicines tends to be price inelastic because these medicines are essential for health and survival, and consumers are often willing to pay higher prices to obtain them.
