The capacity of a switchgrass$-$fueled ethanol plant is $100,000$ gallons per month. Its capital investment is $$600,000.$ Another design is being considered with a capacity of $40,000$ gallons per month, and its capital investment is $$300,000.$ Based on capital investment only, what is the costcapacity factor for this technology?

A$.0\mathrm{.}244$

B$.0\mathrm{.}756$

C$.-0\mathrm{.}756$

D$.$ We don't have enough data to find the cost$-$capacity factor
