Autoimmunity is the system of immune responses of an organism against its own cells and tissues. It is the abnormal immune response in which immune system attacks healthy cells.
Thus, the correct answer is option B.

Autoimmune disease is a condition in which our own immune system attacks our own tissues. Rheumatoid arthritis is an autoimmune disease that causes chronic inflammation of the joints.
Grave's disease is an autoimmune disease in which the patient;s own immune system attacks the thyroid gland causing it to produce too much of thyroid hormone.
Hashimoto's disease is an autoimmune condition caused by inflammation of the thyroid gland.
Thus, the correct answer is option D.

An allergy is a hypersensitivity disorder of the immune system. Symptoms include red eyes, itchiness, and runny nose, eczema, hives, or an asthma attack. Out of the given options, only asthma is an allergy. Asthma and allergies often go hand-in-hand. Asthma is a disease of the branches of the windpipe (bronchial tubes), which carry air in and out of the lungs. There are several different types of asthma. Allergic asthma is a type of asthma that is triggered by an allergy (for example, pollen or mold spores).

• Antihistamines are drugs which are used to treat allergic rhinitis and other allergies. Antihistamines can give relief when a person has nasal congestion, sneezing, or hives because of pollen, dust mites, or animal allergy. Histamine is mostly responsible for allergic reactions. Antihistamines block the action of histamines.
  
• A steroid is a biologically active organic compound. Steroids such as corticosteroids are used in the treatment of allergic reactions by reducing inflammation associated with allergies. They prevent and treat nasal stuffiness, sneezing, and itchy, runny nose due to seasonal or year-round allergies. They can also decrease inflammation and swelling from other types of allergic reactions
  
• So, the correct answer is 'Allergy'.

An autoimmune disease is a condition arising from an abnormal immune response to normal body tissue. In an autoimmune disease, the immune system fails to recognize self-cells and produces antibodies against self-cells. Common symptoms include low-grade fever and feeling tired. Autoimmune disease is due to genetic abnormality or other environmental factors. 

The undesirable responses or reaction to any foreign particles produced by the immune system is known as hypersensitivity. These reactions will result into allergic reaction and auto immunity.

Innate immunity works without concern about how much damage happened but to protect the body and the body exposed to an antigen in an environment develops natural innate immunity.

Autoimmune diseases are disorders in which the bodys immune system attacks the body's own cells and organs with proteins called autoantibodies; this process is called autoimmunity. The bodys immune system normally makes large numbers of proteins called antibodies to help the body fight off infections. In some cases, however, the body makes autoantibodies. Examples include systemic lupus erythematosus (SLE), Sjgren's syndrome, Hashimoto's thyroiditis, Graves' disease, idiopathic thrombocytopenic purpura, Addison's Disease, rheumatoid arthritis (RA), polymyositis (PM).
