Expert needed.....OG2017- Strengthen Question

Mo2men wrote:The air quality board recently informed Coffee Roast, a small coffee
roasting firm, of a complaint regarding the smoke from its roaster.
Recently enacted air quality regulations requires machine roasting more
than 10 pounds of coffee to be equipped with expensive smoke-dissipating
afterburners. The firm, however, roasts only 8 pounds of coffee at a time.
Nevertheless, the company has decided to purchase and install an
afterburner.

Which of the following, if true, most strongly supports the firm’s decision?

A) Until setting on the new air quality regulations, the board had
debated whether to require afterburners for machines roasting
more than 5 pounds of coffee at a time.
B) Coffee roasted in a machine equipped with an afterburner has its
flavor subtly altered.
C) The cost to the firm of an afterburner is less than the cost of
replacing its roaster with a smaller one.
D) Fewer complaints are reported in areas that maintain strict rules
regarding afterburners.
E) The firm has reason to fear that negative publicity regarding the
complaints could result in lost sales.

Why C is wrong?

For me the choice was between D and E. Both the options seem to give Coffee Roast enough incentive to install the afterburner. The experts have explained why E is correct and it makes sense because the decision is purely money-driven. Option D basically says that if Coffee Roast complies with strict rules regarding afterburners, that is, installs the afterburner, the complaints would go away which is what it wants. I get why E is correct, but while under time-pressure, how could we decide between D and E?
