What provides information and symbols attached to a product that detail its context, usage, and safety?

The correct choice, which is labelling, plays a crucial role in conveying essential information about a product. Labelling refers to the printed information that is attached to the product's packaging or container. This information typically includes details such as the product's name, ingredients, instructions for use, safety precautions, and any regulatory compliance markings.

Labelling goes beyond merely being an attractive design; it serves practical purposes that are critical for consumers. For instance, it can inform users about how to safely and effectively use the product, what to do in case of emergency, and any potential allergens or risks. Additionally, labelling can include important symbols and certification marks that signify the product's qualities or compliance with certain standards.

While packaging also contributes to the presentation and protection of the product, and can contain labelling elements, it primarily serves the function of containing and displaying the product rather than specifically detailing its context and usage. Market research and advertising are important marketing components as well, but they focus on gathering consumer insights and promoting the product, rather than providing the direct product information that labelling offers.
