Which category is designated for ordinary natural wood boxes?

• A. A Natural Wood Box Category, Sift-Proof Walled Natural Wood Box
• B. A Metal Box Category, Aluminum Boxes
• C. Plywood Boxes, They Must Consist of at Least 3-Ply Plywood Made From a Well-Seasoned Rotary Cut, and Be Commercially Dry and Free From Defects
• D. A Natural Wood Box Category, Ordinary Natural Wood Box

Answer: (D)

Ordinary natural wood boxes are classified under the Natural Wood Box Category as Ordinary Natural Wood Box. This label describes a standard, unmodified wooden box used for general packing. The other options describe boxes with special features or different materials—such as a sift-proof variant, metal boxes, or plywood boxes with specific construction requirements—so they belong to different categories.
