Answer:
D. iv only
Step-by-step explanation:
Depreciable cost is defined as the difference between acquisition cost of the assets less the salvage value.
Depreciable cost = Acquisition cost - Salvage value.
Depreciable cost refers to the amount invested in the asset which will be depreciated over the useful life of the asset. While calculating depreciable cost, salvage value is subtracted from the acquisition cost. Since salvage value reduces the investment made in the asset.
