The slope of the isoquant represents the rate at which one input can be substituted for another while keeping the same level of output. This can be measured by the ratio of the marginal productivities of the inputs, as this reflects the additional output that can be produced by adding more units of one input while holding the other inputs constant. Therefore, option C is the best choice. The slope of an isoquant measures the rate at which one input can be substituted for another while holding output constant. This means that the slope is determined by the marginal rate of technical substitution (MRTS) between the two inputs. The MRTS is the ratio of the marginal productivities of the two inputs. Therefore, choice C, "the ratio of the marginal productivities of the inputs," is the best choice.
