Which component of human milk is destroyed by freezing?

Lipids
Macrophages
Immunoglobulins
Proteins

The correct answer is: Macrophages

Macrophages are white blood cells present in human milk that play a vital role in the baby's immune system. Freezing human milk can destroy these active immune cells, which are crucial in providing protection against infections and illnesses. While freezing human milk can cause some loss of other components like lipids, immunoglobulins, and proteins, it is the destruction of the macrophages that makes this choice the correct answer.
