A. decreasing taxable income, thus reducing taxes.

Explanation:

Depreciation is an accounting technique that spreads the cost of a physical asset over its useful life. The cost of an asset is divided by the number of its useful years using an appreciate formula. Depreciation is in line with the expense and income matching principle.

The depreciation amount for each year is treated as an operating expense to the business. It is deducted from the gross profits while calculating net profits. Depreciation reduces the net profit and, consequently, taxable income.  It, therefore, reduces the amount payable as tax.
