Final answer:
The statement is true; without revenues, the best alternative is the one with the lowest present discounted total cost. Present discounted value plays a key role in financial decision-making across varied scenarios.
Step-by-step explanation:
The statement that in a situation where no revenues are involved, the most desirable alternative is the one with the least total cost from a present value perspective is true. Present discounted value is an essential analytical tool used to make financial decisions in various contexts. Whether it's a business comparing present costs of an investment to expected future benefits, a government assessing the costs and benefits of public policy changes, or individuals evaluating future lottery payments, assessing the present value of future cash flows is vitally important. When revenues are not a factor, the alternative with the least total costs considering present value will be the most desirable option.
