ACCOUNTING POLICY

According to IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, how should a material error in the previous financial reporting period be accounted for in the current period? A By making an adjustment in the financial statements of the current period through the statement of profit or loss, and disclosing the nature of the error in a note. B By making an adjustment in the financial statements of the current period as a movement on reserves, and disclosing the nature of the error in a note. C By restating the comparative amounts for the previous period at their correct value, and disclosing the nature of the error in a note. D By restating the comparative amounts for the previous period at their correct value, but without the requirement for a disclosure of the nature of the error in a note. THE ANS IS C DOUBTS- in the text they have stated that prior period erros should be accounted for as follows- ? Restating current period figures as if the error never happened correcting those errors ? Restating comparative figures as if error never occurred so would't C be wrong since disclosing the error by note means that we are showing the error has occured but in the text they have shown that the restate if as if the error never happend? so could you please explain how errors are accounted for? thanks in advance
