Final answer:
The measure of results in life-cycle cost benefit analysis is best expressed in net present value (NPV), which discounts future benefits and costs to their present values for comparison and decision making.
Step-by-step explanation:
In life-cycle cost benefit analysis, which is a fundamental aspect of evaluating expenditures and investments over time, the measure of results is best expressed in C. net present value (NPV). This method of analysis involves discounting future costs and benefits to their present value, making it easier to compare them directly as it adjusts for the time value of money. NPV is crucial in a variety of situations, from personal finance, such as understanding the value of lottery payments, to significant societal decisions, like creating government policies for environmental protection and determining the cost-effectiveness of reducing carbon dioxide emissions. NPV helps to bridge the understanding of the present cost against the backdrop of long-term future benefits, regardless of the field of application, be it finance, government planning, or environmental policy-making.
