Verified step by step guidance

1. Step 1: Understand the nature of depreciation expense. Depreciation expense represents the allocation of the cost of a tangible asset over its useful life and is recorded as an expense on the income statement.
2. Step 2: Recognize the classification of accumulated depreciation. Accumulated depreciation is a contra-asset account, meaning it is linked to an asset account but has a credit balance that reduces the asset's book value on the balance sheet.
3. Step 3: Recall that expenses increase with debits and accumulated depreciation increases with credits. Therefore, depreciation expense is an expense account (debit balance), and accumulated depreciation is a contra-asset account (credit balance).
4. Step 4: Review the options given: Asset account and liability account; Expense account and contra-asset account; Contra-asset account and expense account; Liability account and revenue account.
5. Step 5: Conclude that the correct classification is 'Accumulated depreciation' as a contra-asset account and 'Depreciation expense' as an expense account, matching the option 'Contra-asset account and expense account'.
