Final answer:
The depreciation for 2016 under IFRS is $10,000.
Step-by-step explanation:
To calculate the depreciation for 2016 under IFRS, we need to determine the annual depreciation expense for the machine and the drum replacement cost. The machine's cost ($100,000) is divided by its useful life (10 years), which gives an annual depreciation expense of $10,000. The drum replacement cost is incurred every 5 years, so for the first 5 years, there is no drum replacement cost. Therefore, the depreciation for 2016 is $10,000. Option a) $10,000 is the correct answer.
