(D) physical barriers

option A is correct

Answer 2

The Answer is:

(A) Cellular barriers - Polymorphonuclear leukocytes and monocytes

• An immune cell having granules containing enzymes that are released during infections, allergic responses, and asthma attacks.
• Polymorphonuclear leukocytes include neutrophils, eosinophils, and basophils.
• A white blood cell called a polymorphonuclear leukocyte.
• Monocytes are a type of leukocyte, sometimes known as a white blood cell.
• They are the most numerous form of leukocyte and have the ability to differentiate into macrophages and typical dendritic cells.
• Monocytes, as members of the vertebrate innate immune system, also impact adaptive immune responses and perform tissue repair roles.
• Phagocytosis is a key component of cellular innate immunity that is carried out by phagocytes, which engulf or devour pathogens or foreign particles.
• Polymorphonuclear leukocytes, tissue dendritic cells, mast cells, and other phagocytes are common examples.
