Concept:Price elasticity of supply measures how responsive quantity supplied is to a change in price.Explanation:When the coefficient of price elasticity of supply is greater than one, i.e. Es>1, the percentage change in quantity supplied exceeds the percentage change in price. This shows that producers are highly responsive to price changes. Such supply is called relatively or fairly elastic. Since the coefficient is greater than one, it is not perfectly elastic, nor inelastic.Answer:D. fairly elastic
