The correct answer is D. The life cycle cost is reduced . In Value Methodology, life cycle cost analysis is used to compare alternatives over the full ownership period, not just by initial cost. Future costs such as operation, maintenance, replacement, repair, and disposal are converted to present value using a discount rate. When the discount rate is higher, future costs are discounted more heavily, meaning their present value becomes smaller.
This does not mean the actual future cash payment disappears; it means that, in present-value terms, money spent in the future is worth less today. Therefore, increasing the discount rate reduces the present value of future cost streams and normally lowers the calculated present-value life cycle cost, especially for alternatives with large costs occurring later in the study period.
Option A is incorrect because discounting is essential when costs occur at different times. Option B is incorrect because changing the discount rate directly changes present-value calculations. Option C is incorrect because a higher discount rate does not increase the present value of future costs; it reduces them.
