What does the valuation principle say about comparing costs incurred at a different time than the benefits?

Group of answer choices

If costs are incurred at the present and benefits at the future, then only compound the benefits.

If costs are incurred at time $0$ and benefits later at time N$,$ then convert the costs to the future and the benefits to the present.

If costs are incurred at the present and benefits at the future, then only discount the costs.

Costs and benefits should be measured at the times that they are incurred because that is reality.

Costs and benefits must be converted to the same period of time$$s values to make a valid decision.
