A traditional quality control process in manufacturing consists of mass inspection of goods only at the end of a production process. A major deficiency of the traditional control process is that:

A. It is expensive to do the inspections at the end of the process.

B. It is not possible to rework defective items.
C. It is not 100% effective.
D. It does not focus on improving the entire production process.

Explanation:
The process used to produce the goods is not thoroughly reviewed and evaluated for efficiency and effectiveness. Preventing defects and increasing efficiency by improving the production process raises quality standards and decreases costs.
