Which of the following is an example of a contra-asset account?

A contra-asset account is an account that is paired with and offsets a specific asset account. Its balance is opposite to the balance of the associated asset account.

An example of a contra-asset account is "Accumulated Depreciation." This account is paired with the asset account "Property, Plant, and Equipment." While the asset account follows a debit increase and credit decrease rule, the contra asset account's balance increases with a credit entry.

In other words, as the value of the asset depreciates over time (due to wear and tear, obsolescence, etc.), the amount of depreciation is credited to the Accumulated Depreciation account, reducing the net book value of the asset.
