The correct option is C 3rd
Human immune defence mechanisms are divided into two types: Non-specific and specific defence.
Non- specific defence – It is a generalized response of the body which fights pathogens by various means like physical barriers, physiological barriers etc. other than antibodies.
Specific defence – It is a specific type of immune response shown by the body against any specific type of infection like antibody-based defence.
Polymorpho-nuclear leukocytes and monocytes are the cellular structures that engulf any living cells via the process of phagocytosis.
Saliva in the mouth and tears in the eyes contain lysozyme enzymes that inhibit the infection of microorganisms. They are the physiological barriers of the first line of defence.
Mucus coating of the epithelium lining of the urogenital tract acts as a physical barrier as it entraps the infecting microorganisms.
Anti-tetanus and anti-snake bite injections are the readymade antigens that give an immediate defence to the individual by stimulating antibody formation.
