Which of the following immunoglobulins are present in high quantities in human milk?

Human milk contains 0.8% to 0.9% protein, 4.5% fat, 7.1% carbohydrates, and 0.2% ash (minerals). 

IgG, IgA, IgM, IgD, and IgE have been found in human milk, but the most abundant type is IgA. The level of immunoglobulin A (IgA) in breast milk remains high from day 10 until at least 7.5 months post-partum.

Hence, option D is the correct answer.
