Final answer:
The missing word in the question is 'purpose,' as a list of ingredients provides what's in a product but not the reason for its use. Other details like expiry date, manufacturer, and cost are usually found elsewhere on the packaging.
Step-by-step explanation:
When examining a list of ingredients on a food label, it provides specific information about what's inside the product. However, it does not provide everything about the product's broader context. The blank in the question you posted should be filled with the word 'purpose' (Option A). Ingredients will tell you what the product contains, but they do not explain why those ingredients are used, that is, the purpose of the product or the benefits it may offer. Other details that are not part of the ingredients list but can be found elsewhere on the packaging include the expiry date, the manufacturer details, and the cost or price of the item. These details are essential for different reasons: the expiry date for safety, the manufacturer for accountability, and the cost for purchasing decisions.
