The correct answer is B .
Pricing is the monetary value placed on a product or service, but in category management it is more than a simple price tag. It is one of the key category tactics because it affects shopper choice, sales volume, gross margin, profit, and overall category performance. CMKG's pricing guidance states that pricing decisions directly affect category sales, inventory positions, and category profitability, and that price is a major influence on shopper purchase behavior.
Option A is wrong because product categorization is segmentation or assortment work, not pricing. Option C is too narrow because production cost is only one input into price setting; pricing also considers competition, shopper value, elasticity, retailer strategy, category role, margins, and promotional objectives. Option D is wrong because promotional discounting is only one pricing tactic. Pricing includes regular price, promotional price, price thresholds, competitive price positioning, private-label gaps, price elasticity, slope, and margin implications.
