Under the cost model, an impairment loss would be recorded as:

A) DR Sales, CR Impairment loss.
B) DR Impairment loss, CR Accumulated depreciation and impairment losses.
C) DR Accumulated impairment losses, CR Impairment loss.
D) DR Accumulated impairment losses, CR Asset revaluation (equity) .

Under the cost model, an impairment loss is recorded by debiting the Impairment loss account and crediting the Accumulated depreciation and impairment losses account. This reduces the carrying amount of the asset on the balance sheet. Therefore, option B is the correct answer. The other options do not follow the correct accounting treatment for recording an impairment loss.
