Choice "D" is correct. For substitute goods, as the price of one good goes up, the demand for another, substitute good increases as consumers desire the lower-priced substitute good.
Choice "a" is incorrect. Superior goods. Just as the demand for inferior goods declines with an increase in the income level of a consumer, superior goods will experience a spurt in demand as prices are raised.
Choice "c" is incorrect. The demands for mutually "complementary goods" fluctuate together (e.g., more cereal purchases are accompanied by an increase in the demand for milk).
Choice "b" is incorrect. Independent goods have unrelated demand functions (e.g., bread and vacuum cleaners).
