Answer: E
Step-by-step explanation:
none of the above because both the straight-line and double declining-balance depreciation methods are not fully depreciating the asset. That is ,when the salvage value is zero,double-declining-balance depreciation method will never depreciate the asset fully.
Moreover income tax paid also will not lower under DDB,method.
Or
Neither method depreciates assets more fully (that is, to the residual value more quickly) than the other. In fact, if the salvage value is $0, the double-declining-balance method will never fully depreciate the asset. The salvage value relative to the original cost and the asset life will determine which method reaches salvage value more quickly.
