d. Year 10 only.

答案：D

Explanation

Choice "d" is correct. Under IFRS, past service cost is recognized on the income statement in the period of the plan amendment. 

Choice "b" is incorrect. No retroactive adjustment is made when a plan amendment is made.

Choice "a" is incorrect. Under IFRS, past service cost is recognized on the income statement in the period of the plan amendment. Retroactive charges to past periods are not made and it is not necessary to amortize the cost to future periods because it has already been recognized in earnings.

Choice "c" is incorrect. Under IFRS, past service cost is recognized on the income statement in the period of the plan amendment. It is not reported in other comprehensive income and therefore recognition in future periods through amortization is not required.
