Step 1: Understanding the Concept:
The question asks for the typical sugar content of flavoured milk. It's important to distinguish between the natural sugar (lactose) present in milk and the sugar (sucrose) added for sweetness. The question likely refers to the amount of *added* sugar.
Step 2: Detailed Explanation:
Plain milk naturally contains about 4.5% to 5% lactose. To make flavoured milk, sugar is added to provide sweetness that complements the added flavour (e.g., chocolate, strawberry).
The amount of added sugar is carefully balanced to make the product palatable without being overly sweet.
Let's analyze the options in the context of *added sugar*:
(A) 4-5%: This is a possible level for a less sweet product, but often a bit higher concentration is preferred.
(B) 2-3%: This amount of added sugar would likely be insufficient to overcome the milk's natural taste and provide a distinctly sweet, flavoured product.
(C) 5-7%: This is the most common commercial range for added sugar in flavoured milk. It provides a good level of sweetness that is widely accepted by consumers.
(D) 12-14%: This level of added sugar would make the product excessively sweet, more like a dessert than a beverage. This range might be closer to the *total* sugar content (lactose + added sugar).
Since the question is asking for a general range and 5-7% is the industry standard for added sugar to achieve the desired taste profile, this is the most appropriate answer.
Step 3: Final Answer:
The typical range for added sugar in flavoured milk is 5-7%.
