  • The correct answer is: D) an increase in the price of beer will lead to an increase in revenue for beer sellers and beer is an inferior good.

Since the demand for beer is inelastic, then an increase in the price of beer will increase the total revenue for beer sellers. Negative income elasticity of demand means that beer is an inferior good. Its demand decreases with an increase in income.
