Solution
The correct option is D Quaternary
Immunoglobulins are large molecules made up of four peptide chains. It contains two identical heavy chains and two identical light chains, thus forming a tetrameric quaternary structure. The two heavy chains are linked to each other and to a light chain each by disulfide bonds. The resulting tetramer has two identical halves, which together form the Y-like shape.
Thus, the correct answer is option (D), 'Quaternary'.
