Answer: The correct answer for the blank is- Autoimmune disease.
When the immune system of the body fails to recognize "self" that is its own body tissue, it produces antibodies against it.
Due to this, the body's own cells, tissues, or organs are targeted, which cause inflammation and damage to the body. This condition develops as autoimmune disease.
Example of autoimmune disease- Multiple sclerosis ( myelin sheath, an insulation around nerve fiber, is destroyed that affects the transmission of nerve impulse resulting in problems related to muscular control).
