Answer:
D. Maximize (outputs - inputs)
Step-by-step explanation:
The input is the raw material, labor, the efforts that is used in making the product while the output is the product or the result arising from the input
The profit arises when output and the input varies from each other
i.e
Profit = Output - input
In the case where there is neither an input nor output fixed, so we have to maximize the profit i.e (output - input) but the condition is that they are different from each other
Hence, the correct option is D.
