The correct answer is D. An isocost curve.
An isocost curve is a graph that shows all the combinations of inputs that a firm can purchase with a given budget. It is a straight line that slopes downward from left to right, indicating that the firm can purchase more of one input only if it purchases less of the other input.
A total cost schedule is a table that shows the total cost of production for a firm at different levels of output. It is derived by multiplying the quantity of each input by its price and adding up the total costs.
The information given in an isocost curve is sufficient to derive a total cost schedule because the isocost curve shows the combinations of inputs that a firm can purchase with a given budget. The firm can then choose the combination of inputs that will produce the desired level of output, and the total cost of production can be calculated from the prices of the inputs and the quantities used.
The other options are incorrect because they do not provide enough information to derive a total cost schedule. An Engle curve shows the relationship between the quantity of a good demanded and the income of the consumer. A price consumption curve shows the relationship between the quantity of a good demanded and the price of that good. An expansion path shows the combinations of inputs that a firm will use to produce different levels of output when the prices of inputs are constant.
