Solution
The correct option is D Killer T cells
In animals, there are two typed of defenses as specific and non-specific defenses. Non-specific defenses include physical barriers, protein defenses, cellular defenses, inflammation and fever.
Barriers: physical barriers such as skin and mucous membranes mechanically regulate what enters the body. Many body secretions such as mucus or tears contain an enzyme called lysozyme that destroys bacteria.
Proteins: complement proteins are found in the blood. When they bind to an invader, they stimulate inflammation, phagocytosis and destruction of the invader's membrane.
Specific defense includes the immune system which includes the T lymphocytes and the B lymphocytes.
Thus, the correct answer is option (D).
