Option (a): The net realizable value (NRV) of an object is the expected return after deducting the cost of selling it. Under IFRS, value-in-use is not defined as a net realizable value.
Option (b):A fair value represents the estimated value of its assets and liabilities. Fair market value refers to an item's sale value that is fair for both buyers and sellers. Fair value is quite different from the value-in-use.
Option (d):Cash flows that have not been modified to account for the time worth of money are known as undiscounted cash flows. This is the polar opposite of discounted cash flows when investment decisions are based only on the nominal value of cash flows.
