The antibodies mistakenly identify the cells as foreign material

Option). The antibodies mistakenly identify the cells as foreign material.

Explanation:

Antibodies identify specific patterns on foreign substances to target them. Antibodies that mistakenly recognize and attack self tissue or organs as foreign substances are known as autoantibodies.

Destruction of self tissues by antibodies lead to various autoimmune disorders, characterized by dysfunction or damage of organs, and inflammation.

Multiple sclerosis  is an example of autoimmune disorder, due to autoantibodies against protective covering of neurons.
