D Correct answer
Explanation

The white color of milk is due to the presence of calcium and the reflection of light by casein proteins and fat globules. Calcium compounds contribute to the opaque white appearance. Iron is not responsible for milk's color, and while proteins and fats are present, calcium is the primary mineral responsible for the white coloration.
