The contra credit preserves $28,000 gross cost, produces a $22,000 carrying amount, and records no cash or appraisal.
Directly crediting Equipment erases gross-cost history, and the allocation supplies no market evidence.
Depreciation is a noncash allocation in this period; the contra credit does not generate or reserve Cash.
A contra-asset ordinarily has the opposite normal side: accumulated depreciation increases with a credit while expense increases with a debit.
Answer: A
One year allocates ($28,000 − $4,000) ÷ 4, or $6,000. Debit Depreciation Expense and credit the credit-normal contra-asset Accumulated Depreciation. Gross Equipment remains $28,000 and carrying amount becomes $22,000. The entry changes neither Cash nor demonstrated market value.
