Indifference curves represent combinations of goods that provide the same level of utility to a consumer. For two combinations to be on the same indifference curve, the substitution between the goods must be consistent. The rate at which orchids can be substituted for lilies (or vice versa) should remain constant along an indifference curve. By comparing the ratios of orchids to lilies in each option, we can determine if one of the combinations does not fit the pattern of substitution implied by the others. A) 12 orchids : 15 lilies = 0.8 orchids per lilyB) 6 orchids : 24 lilies = 0.25 orchids per lilyC) 9 orchids : 10 lilies = 0.9 orchids per lilyD) 15 orchids : 12 lilies = 1.25 orchids per lilyOptions A, B, and D can be seen as having a consistent substitution pattern when considering the ratios and the possibility of scaling up or down. However, option C, with 9 orchids and 10 lilies, does not fit this pattern as neatly, indicating it cannot be on the same indifference curve as the other three based on the implied rate of substitution.
