The minimum hazard marking size for GMO packaging is 50 mm by 50 mm.

• A. 40 mm x 40 mm
• B. 60 mm x 60 mm
• C. 50 mm x 50 mm
• D. 100 mm x 100 mm

Answer: (C)

The emphasis here is on legibility and standardization of hazard labeling. The minimum size for a GMO packaging hazard marking is 50 by 50 millimeters because this dimension is large enough to be easily read and recognized by handlers, inspectors, and receiving personnel without crowding the label on typical packaging surfaces. Anything smaller, like 40 by 40, could be too difficult to read in real-world handling conditions, which is why it’s not acceptable as the minimum. Larger sizes, such as 60 by 60 or 100 by 100, are allowed, but they exceed the minimum requirement; the question asks for the smallest size that satisfies the rule, so 50 by 50 millimeters is the correct answer.
