Answer: A. The other asset group should be tested for an impairment loss before goodwill is tested.
Explanation:
According to the IFRS standards, it is important and necessary to revalue your assets according to their net realizable value, i.e, assets should be reported after deducting accumulated depreciation or amortization in the case of goodwill. In the case of inventory, NRV should be calculated by estimating impairments.
The other asset groups are tested to check for impairment loss and later the goodwill is tested.
