What is the primary or main immunoglobulin in human milk?

  1. IgA

  2. IgG

  3. IgE

  4. IgM

The correct answer is: IgA

IgA is the primary immunoglobulin in human milk. Human milk is rich in IgA, which protects infants from various infections and helps to support their developing immune systems. IgG is the most abundant immunoglobulin in the human body, but it is not the primary immunoglobulin in human milk. IgE and IgM are also present in human milk, but in smaller amounts compared to IgA.
