Depreciation and amortization are both methods used for spreading the cost of assets over time, but they apply to different types of assets. Depreciation applies to tangible assets such as machinery, buildings, and vehicles. These assets have a measurable physical form and their value decreases due to usage, wear-and-tear, or aging. The reduction is spread over the declared useful life of the asset.
Amortization applies to intangible assets such as patents, trademarks, copyrights, goodwill, and software. These assets do not have physical form, and instead of a declared life, a specified time period (legal validity or contractual duration) is used for spreading the cost.
Thus, option (A) correctly matches depreciation with tangible assets and amortization with intangible assets.
