Answer:
The correct answer is letter "B": Present value of depreciation expense.
Step-by-step explanation:
Depreciation indicates how much an asset's value has been used up. It also tries to match the expense of an asset to the income the asset helps the company earn. Depreciation is not a cash expense but it affects the profits of a firm, thus, it must be considered in the cash flow at the moment of calculating the net present value.
