Answer:
The correct answer is C. the decline in the economic value of an asset over time
Explanation:
Depreciation : Depreciation is a decreasing value of the asset due to tear and wear, obsolesce, usage, etc
It is charged on the fixed assets which include plant and machinery, furniture and fixtures, building, computer, equipment, etc.
The sum of gross and net investment is not called the depreciation because gross investment is an expenditure which is incurred on new purchase while net investment is a difference between gross investment and deprecation. So, option B is incorrect.
Depreciation should not be charged on intangible assets because in intangible asset, the amortization is charged. Thus, option B is incorrect.
The decrease in the general price level is disinflation or inflation decreased. So, option D is also wrong
Hence, The correct answer is C. the decline in the economic value of an asset over time
