Which of the following most logically completes the argument below?
Nessus Valley Machinery is trying to decide between manufacturing screws out of steel or screws out of aluminum. Both types of screw typically cost about the same to produce and they sell at comparable prices. Because one of Nessus Valley's primary customers, an automotive company, is discontinuing the truck they produce that uses steel screws, the market for steel screws, though not for aluminum screws, will be significantly smaller than usual. Therefore, producing screws from aluminum will be more profitable than producing screws from steel, because __________ .
A. the smaller-than-usual customer base for steel screws will not be offset by a higher sales price for steel screws
B. an additional production run of steel screws should be planned for when the market returns to normal levels
C. the steel screws Nessus Valley produces are better for use in trucks than their aluminum equivalent
D. aluminum screws can only be used for certain products
E. producing aluminum screws is more profitable than producing screws from other types of metal, such as titanium
