By what maximum percentage can the count of stalks packed in bunches vary from their bunch designation?

The correct answer is based on the regulations pertaining to the packaging and labeling of agricultural commodities, specifically regarding the labeling of bundle sizes. According to industry standards and regulatory guidelines set forth by the Commodity Regulatory Programs, the maximum allowable variation in the count of stalks packed in bunches relative to their designated size is typically 10%. This means that if a bunch is designated to contain a specific number of stalks, it can vary by up to 10% more or less without this being considered a violation of the labeling regulations.

The rationale for allowing some degree of variation is to accommodate the natural inconsistencies that occur during packing and handling, as products can have variations in size and weight. A tolerance of 10% ensures that consumers receive a product that is fairly representative of what is labeled, keeping in mind the intrinsic variability of agricultural products.

In contrast, the other options specify higher percentages, which would exceed the typical tolerance levels established to maintain fairness in the marketplace and ensure consumer protection. Options indicating larger variations do not align with the regulatory standards intended to promote transparency in labeling and to protect both consumers and producers in the agricultural commodities sector.
