• A. Human milk
• B. Cow milk
• C. Buffalo milk
• D. Camel milk

Hint:

Answer 1

The Correct Option is A

Step 1: Understanding the Question
The question asks to identify which type of milk from the given options contains the highest percentage of lactose (milk sugar).
Step 2: Detailed Explanation
The composition of milk varies significantly across different mammalian species. Lactose is the primary carbohydrate in milk.
A comparison of typical lactose content:

Human milk: Contains about 7.0\% lactose. This high sugar content provides the necessary energy for the rapid brain development of human infants.

Cow milk: Contains about 4.8\% lactose.

Buffalo milk: Contains about 4.9\% lactose.

Camel milk: Contains about 4.4\% lactose.

Comparing these values, human milk clearly has the highest concentration of lactose.
Step 3: Final Answer
The highest lactose content is found in human milk.
