Answer:
b.The good is a necessity
Explanation:
The price elasticity of demand = percentage change in quantity demanded/ percentage change in price
3% / 12% = 0.25
When the coefficient of elasticity is less than one, demand is inelastic.
Inelastic demand means that when price increases, there is little or no change in quantity demanded.
Necessity goods are goods that are very important to consumers and thus they tend to have an inelastic demand. For example, medications.
Substitute goods are goods that can be used in place of another good because of their similarity. E.g. butter and margarine
Goods with many substitutes have an elastic demand. If price of a good increases, consumers can easily shift consumption to substitute goods.
Narrowly defined goods have an elastic demand because it is easier to find subsituites for such goods.
Demand is more elastic in the long run because consumers have more time to search for substitutes.
