Total amount of depreciation charged on long term assets is classified as

accumulated depreciation

The correct answer is A. accumulated depreciation.

Accumulated depreciation is the total amount of depreciation that has been charged against a long-term asset. It is a contra-asset account, which means that it is deducted from the asset account on the balance sheet. Accumulated depreciation is used to account for the decrease in the value of an asset over time due to wear and tear, obsolescence, and other factors.

Depreciation is a non-cash expense, which means that it does not reduce cash flow. However, it does reduce taxable income, which can result in tax savings.

Accumulated appreciation is the total amount of appreciation that has been recorded for an asset. Appreciation is an increase in the value of an asset over time. It is not a common accounting concept, and it is not typically used for long-term assets.

Accumulated appreciation schedule is not a valid term.
