ANS:B - disposing off machine/property, which is no longer useful in the present scenerio.

In the context of financial investment analysis, "salvaging" typically refers to disposing of a machine or property, which is no longer useful in the present scenario. Salvage value represents the estimated residual value of an asset at the end of its useful life. It is the amount that could be obtained from selling the asset if it were to be disposed of at the end of its useful life. This value is important in financial analysis, particularly in calculating depreciation and determining the overall return on investment. So, the correct definition of "salvaging" in this context would be disposing of a machine or property that is no longer useful, hence the salvage value would be obtained by selling or salvaging the asset. It doesn't involve mortgaging or writing off the obsolete machine or property.
