Hill Milling is currently reviewing a proposed project that aims to determine the feasibility of expanding its product line. The company's sales projections for the new product line are $8,000$ units, with a margin of error of plus or minus $2$ percent. It is expected that each unit will incur a variable cost of $$11,$ while the fixed costs for the project are estimated to be approximately $$287,000.$ The estimates for both fixed and variable costs are accurate within a range of plus or minus $5$ percent, as per the company's projections. The project's depreciation expense is expected to be $$68,000,$ and the tax rate is set at $32$ percent. Assuming that the product will be sold at the estimated price of $$64$ per unit, with an error margin of plus or minus $3$ percent. What would be the operating cash flow under the best$-$case scenario?

A$.$ $$107,146$

B$.$ $$148,475$

C$.$ $$168,630$

D$.$ $$144,150$

E$.$ $$174,220$
