The correct answer is B .
Space and assortment are interdependent. CMKG directly states that space planning and efficient assortment are both very important and explains that many roles across the organization make decisions affecting product assortment and the shelf. CMKG also warns that planograms and assortment work must consider out-of-stocks, turns, profit, sales, inventory, shopper needs, and retailer strategy.
Option B is the only answer that captures the two-way relationship. Available shelf space can limit how many items, sizes, brands, and segments can fit. At the same time, assortment choices influence how much space must be allocated to each segment, brand, or SKU.
Option A is wrong because assortment cannot be finalized without space constraints. Option C is also wrong because space alone does not determine the assortment; shopper demand, category strategy, item productivity, and role matter. Option D is completely wrong because space planning and assortment planning should not be handled independently.
