When the price of a good declines, the marginal rate of substitution changes, leading consumers to buy more of that good. O B. When the price of a good rises, the ratio of the marginal utility to price falls, leading consumers to buy less of that good. O C. When the price of a good declines, this causes positive substitution and income effects, leading consumers to buy more of that good. O D. When the price of a good rises, this causes a negative income effect that is larger in absolute value than a corresponding positive substitution good. O E. When the price of a good rises, the budget constraint shifts outward, leading consumers to buy less of that good
