b. True or False. "A rational consumer will purchase only 1 unit of the product represented by these data, because that amount maximizes marginal utility."

O True, because marginal utility falls after consuming the first unit. c. True or False. "It is possible that a rational consumer will not purchase any units of the product represented by these data." O True, because this product's price could be high relative to the first unit's marginal utility. O False, because this product's price could be low relative to the first unit's total utility. O True, because this product's price could be high relative to the first unit's total utility. O False, because this product's price could be low relative to the first unit's marginal utility.
