Question 1: Keyword in Answer 1 = Only, IFRS can revalue any assets.
Question 2: The Revalue allowed, but is shown in a Valuation Allowance (Contra Account), as opposed to the asset itself being revalued once it is written down, Profit/loss is shown on IS at time of sale. For Answer 2, they can be revalued above original value, but the gain recognized on IS may only be up to the amount of the original write down. Then, it would hit S/E to balance out the higher asset level. But the asset may be revalued higher (going to need disclosures about date, process etc.)
BTW, Logically, if Question 2 is Answer A, then Question 1 Cannot possibly be Answer C (Least accurate and Most accurate probably won’t be the same answer)
