Which of the following would be considered as an incidence of misbranding?

Misbranding occurs when a product's labeling is misleading or false, particularly in the context of its identity, composition, or the claims made about it. The situation where the label indicates that the alcohol content is 15% V/V, while the actual content is only 5% VN, is a clear case of misbranding. This discrepancy directly affects the consumer's understanding of the product, as it misrepresents its strength and potential effects. Providing incorrect alcohol content can lead to significant legal and safety implications, as consumers expect products to provide accurate information for responsible consumption.

In contrast, while the other scenarios present issues, they do not constitute misbranding in the same manner. For instance, stating an incorrect weight or volume may lead to labeling violations, yet it won't necessarily mislead consumers about the product's safety or effects as dramatically as a false alcohol percentage. The lack of child-resistant packaging or outdated expiration dates also involves regulatory compliance issues, but these do not directly alter the fundamental truthfulness of the product’s identification and its quality. Hence, labeling false information about the alcohol concentration represents a clear instance of misbranding.
