The correct answer is D.

The CPCM pricing analytics course covers advanced analytic techniques used to assess retailer pricing, including price-setting rules and methods used to evaluate pricing decisions. Price elasticity is one of the core pricing analytics concepts because it measures how demand responds when price changes. Harvard Business Review defines price elasticity as showing how responsive customer demand is for a product based on its price.

Option D is the only answer that correctly describes price elasticity. It is about demand sensitivity to price changes.

Option A is wrong because product quality and satisfaction are consumer perception measures. Option B is seasonality analysis. Option C is advertising or promotion response analysis. None of those define price elasticity.
