The correct answer is C .
Retail supply chain is broader than transportation and warehousing. CMKG is very clear that supply chain is “much more than” moving products and that it affects inventory, forecasting, availability, cash flow, service levels, and shopper experience. That directly supports option C because retail supply chain includes the connected processes and systems that move product efficiently while protecting freshness, cost, availability, and customer satisfaction.
Option A is incomplete because transportation and storage are only part of the supply chain. Option B describes promotion and marketing, not supply-chain management. Option D describes financial planning, which is important, but it is not the full definition of retail supply chain. The best answer must include product flow, waste reduction, freshness, cost, availability, and shopper impact.
