The comprehensive process involving all activities from product conception to post-sales service is known as supply chain management, which is the correct answer to the student's question.
Step-by-step explanation:
The set of activities required to design, develop, produce, market, deliver, and provide post-sales service for the products and services sold to customers is known as supply chain management (c). Supply chain management encompasses the entire process from design to post-sales, including finding suppliers, creating manufacturing facilities, and handling sales and marketing, as seen in the example of the alternate commuter vehicle design. The notion of production, as described through the example of pizza making, involves the transformation of inputs like labor, capital, and raw materials into final products or services ready for customers. This transformation process is just a part of the entire supply chain management.
