What is the primary characteristic of inelastic products?

The primary characteristic of inelastic products is that they are necessities that consumers buy consistently. Inelastic products have a demand that does not significantly change with variations in price; even if the price rises, consumers will continue to purchase these items because they are essential for their daily lives. Examples include basic food staples, medicines, and utilities. Because these products are considered necessities, consumers prioritize purchasing them regardless of price fluctuations, which leads to a relatively stable demand.

Luxury items, while potentially inelastic for certain consumers, are generally more elastic because their purchase can be deferred or avoided when prices rise. The other options refer to products that either lack demand or are seldom purchased, which do not accurately describe inelastic products that maintain steady sales due to their essential nature.
