Answer: a. a just-in-time inventory system.
Explanation: The new system, which will focus on reducing or completely eliminating carrying costs, will employ a just-in-time inventory system which is defined as the inventory management approach that attempts to minimize, if not eliminate, carrying and stockout costs. This serves to improve efficiency, while reducing significantly, wastes in the production process, and minimize inventory carrying costs as it only receives production inputs only as needed in the production process.
