Step 1: Understanding production design.
Production design involves planning how a product will be manufactured, focusing on cost, efficiency, quality, and customer satisfaction.
Step 2: Division of production design.
The process of production design is generally divided into four categories: product design, process design, tool design, and operation design.
Each category plays a different role but together ensures the efficiency of production.
Step 3: Option analysis.
- (A) Two categories: Too limited and incomplete.
- (B) Three categories: Incorrect, leaves out important aspects.
- (C) Four categories: Correct, it is standard classification.
- (D) Six categories: Not a valid division in basic theory.
Step 4: Conclusion.
Hence, the process of production design is divided into four categories.
