Solution

The correct option is A S
Immunoglobulins are glycoprotein molecules that are produced by plasma cells in response to an immunogen and which function as antibodies. All immunoglobulins have a four-chain structure as their basic unit. They are composed of two identical light chains and two identical heavy chains. Immunoglobulins contain an interchain and intrachain disulfide bonds. Hence, the element required to maintain the structure of immunoglobulin is Sulphur.
So, the correct answer is 'S'.
