The correct answer is (D) Protein A of Staphylococcus aureus.
Protein A is a surface protein of Staphylococcus aureus that helps the bacteria evade the host’s immune system by binding to the Fc region of antibodies, preventing them from recognizing and attacking the bacteria. However, it does not directly interfere with the body’s attempt to localize infection.
