The correct answer is D .
The CPCM course identifies Promotion Analysis Techniques as a formal CPCM curriculum area and states that promotional assessment includes "incrementality of the promotion," promotional price, ad space and positioning, display support, seasonality, and competition. It also states that promotion calculations include
"return on investment" and that learners must "assess promotional effectiveness using a return on investment approach." ROI analysis is therefore not just a sales-volume check. It measures whether the promotion produced enough incremental financial return to justify the money, margin, discount, display, ad space, or funding invested in it. A promotion can generate high sales but still be a weak ROI event if the lift is heavily subsidized, margin is sacrificed, or sales are mostly cannibalized from normal purchases.
Option A is wrong because cost savings alone are not ROI. Option B is wrong because customer satisfaction is not the financial ROI measure. Option C is incomplete because total sales volume ignores cost, margin, incremental sales, and investment.
