B

Explanation:
The correct answer is B because production planning and control involves reconciling the demand for resources and outputs with their supply to ensure efficient operations. This process includes scheduling, resource allocation, and output management to meet production goals. Option A, inventory management, focuses on stock levels, not the broader reconciliation of resources and outputs. Option C, capacity planning and control, deals with matching production capacity to demand but is less comprehensive than production planning. Option D, quality control, focuses on product standards, not resource reconciliation.
