The correct option is (a) depreciation expense increases.
A measure of the amount of money made by a company's regular business operations is called operating cash flow (OCF). Operating cash flow shows if a business can produce enough positive cash flow to support and expand its operations; if not, it may need outside finance for capital growth.
While cumulative depreciation is the overall amount of wear and tear to date, depreciation expense is the amount that a company's assets are depreciated for a specific period (such as a quarter or the year). Accumulated depreciation is neither an expense, nor is it a depreciation expense.
