Step 1: Understanding the Concept:
The question concerns the typical *added* sugar content in flavored milk, not the naturally occurring lactose. We need to consider the sucrose added for sweetness.
Step 2: Detailed Explanation:
Plain milk contains approximately 4.5% to 5% lactose. Flavored milk has sugar added to complement the flavor (e.g., chocolate, strawberry).
The amount of added sugar is carefully adjusted for optimal palatability.
Analyzing the options based on *added sugar* content:
(A) 4-5%: This could be used for a less sweet product, but often a slightly higher concentration is preferred.
(B) 2-3%: This amount of added sugar is likely insufficient for a distinctly sweet, flavored product due to the milk's natural taste.
(C) 5-7%: This is the most common commercial range for added sugar in flavored milk, providing widely accepted sweetness.
(D) 12-14%: This level of added sugar would result in excessive sweetness, making the product more like a dessert. This range may represent the *total* sugar content (lactose + added sugar).
The question asks for a general range; 5-7% is the industry standard for added sugar to achieve the desired taste profile, making it the most suitable answer.
Step 3: Final Answer:
The typical added sugar range in flavored milk is 5-7%.
