Explanation

Milk is a well-established rich source of Vitamin A (retinol), which is found in milk fat and is vital for vision and immune health.
It is also an excellent source of Vitamin B2 (riboflavin), a key coenzyme in energy metabolism.
Most commercially available milk is fortified with Vitamin D to enhance calcium absorption, making it a significant dietary source for this vitamin, which is crucial for bone health.

Option B: Milk is a poor source of both Vitamin C and Vitamin K. Vitamin C is heat-sensitive and largely destroyed during the pasteurization process. Vitamin K is primarily found in green leafy vegetables and is synthesized by gut bacteria.
Option C: Milk is not a significant source of Vitamin E. The richest sources of Vitamin E are vegetable oils, nuts, seeds, and green leafy vegetables.
Option D: While milk does contain Vitamin B12, it is most celebrated for its high content of Vitamin B2 (riboflavin). It is not considered a primary rich source of Vitamin B6. Therefore, the combination in the correct option is more accurate.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Nutritional composition of milk, specifically its vitamin content as background academic context rather than a clinical decision trigger.
Understanding milk's nutritional profile is crucial for patient education regarding bone health, as the combination of calcium and Vitamin D is synergistic.
Nurses must be aware that while milk is excellent for growth, an exclusive milk diet after 6 months of age can lead to iron-deficiency anemia in toddlers.
For exclusively breastfed infants, the American Academy of Pediatrics recommends Vitamin D supplementation from the first few days of life, as breast milk may not provide enough.

How to Approach the Question

This is a factual recall question that tests your knowledge of basic nutrition.
First, identify the keywords in the question: 'Milk' and 'rich source'.
Evaluate each option based on your knowledge. Recall the major nutrients milk is known for (calcium, protein) and what it lacks.
A key piece of information to remember is that milk is a poor source of Vitamin C and Iron. This immediately helps to rule out any options containing these.
Option B contains Vitamin C, so it can be eliminated.
Compare the remaining options. Milk is widely known to be a good source of Vitamin A and is almost always fortified with Vitamin D. It is also one of the best dietary sources of Vitamin B2. This makes the combination in the first option the most accurate and complete answer.
