Answer 1

Hint: Autoimmunity is a condition in which the immune system loses its ability to distinguish the self and non-self structures.

Complete answer: The self immune system is unique to each human body that means it is unique for each individual and is developed as the individual gets ill.
1. The self immunity system refers to the immune system of the body that can find the foreign agents that are antigens which can be various bacteria or fungus or virus.
2. Autoimmunity refers to the ability of the immune system to fight against the self that destroys its cells.
3. It is a kind of neurodegenerative disorder in which the cell has lost the ability to distinguish between self and non-self.
4. Autoimmunity causes various diseases such as Rheumatoid arthritis, multiple sclerosis, and many more.
5. A specific immune system refers to the immune system that is specific to a particular antigen that can be a self or non-self cell but generally it is non-self.
6. It is specific for each antigen and produces antibodies upon interaction with a particular kind of antigen.

Therefore, option B that is autoimmunity is the correct option.
