The correct answer is A. Depreciation.
Depreciation is the decrease in the value of an asset over time due to wear and tear, age, and obsolescence. It is a non-cash expense that is used to account for the decline in the value of an asset over its useful life.
Accumulated depreciation is the total amount of depreciation that has been recorded for an asset since it was acquired. It is a contra-asset account, which means that it is deducted from the asset account on the balance sheet.
Appreciation is an increase in the value of an asset over time. It is a non-cash event that is not recorded in the financial statements.
Written down value (WDV) is the book value of an asset after depreciation has been taken into account. It is calculated by deducting the accumulated depreciation from the original cost of the asset.
