Antibody are produced by B-lymphocytes. The plasma cell /plasma B cells/effector B cell are white blood cells that secrete large volumes of antibodies. Plasma cell originates in the bone marrow.B cell differentiate into a plasma cell that produces antibody molecules. These are transported by the blood plasma and the lymphatic system. Once these are released into the blood and lymph, these antibody molecules bind to the target antigen and initiate its neutralization or destruction.

Immunoglobulin also known as antibodies are glycoprotein molecules produced by plasma cells (white blood cells). They act as a critical part of the immune response by specifically recognizing and binding to particular antigens, such as bacteria or viruses and help in their destruction.The antibody immune response is highly complex and exceedingly specific. Hence, antibodies are complex glycoproteins.

An antibody which belongs to the class of immunoglobulin is a large, Y-shaped protein which is produced mainly by plasma cells and it is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses. Antibodies are secreted by B lymphocytes of the adaptive immune system, mostly by differentiated B cells called plasma cells. 

Immunoglobulins, also known as antibodies, are glycoprotein molecules produced by plasma cells (white blood cells). They act as a critical part of the immune response by specifically recognising and binding to particular antigens, such as bacteria or viruses, and aiding in their destruction. So, the correct option is 'Glycoproteins'

Antibodies (also called immunoglobulins) are large proteins. They are found in the blood or other body fluids of vertebrates. Antibodies are the key element in the adaptive immune system. The antibody recognizes a unique part of the foreign target called an antigen. It is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses. Antibody is produced by plasma cells. Antibodies can occur in two physical forms, a soluble form that is secreted from the cell to be free in the blood plasma, and a membrane-bound form that is attached to the surface of a B cell and is referred to as the B-cell receptor (BCR). 

IgE is an immunoglobulin that plays a central role in acute allergic reactions and chronic inflammatory allergic diseases.

• Body's defence system produces antibodies.
  
• Antibodies are produced when an allergen or a foreign substance enters the human body by the immune system.
• It protects the body from unwanted foreign particles which enter the body.
• So, the correct answer is 'False'.

Mast cells are coated with IgE, which is produced by plasma cells (the antibody-producing cells of the immune system). IgE antibodies are typically specific to one particular antigen. In allergic reactions, mast cells remain inactive until an allergen binds to IgE already coated upon the cell.

Antibodies are the immunoglobulins which are produced in response to the antigen. The immunoglobulin E antibodies or IgE binds to an allergen and trigger the release of inflammatory chemicals such as histamine.
Therefore, the correct answer is option A.
