The correct answer is: D. A calculated value, which keeps on decreasing.
Depreciation is the process of allocating the cost of an asset over its useful life. The calculated value of an asset decreases each year as it is used. This is because the asset is losing value over time due to wear and tear, obsolescence, and other factors.
Option A is incorrect because the original cost of an asset is not used to calculate its depreciation value. Option B is incorrect because the projected value of an asset is not used to calculate its depreciation value. Option C is incorrect because the calculated price of an asset does not remain the same over time.
