"Severe combined immunodeficiency (SCID) " can be caused by "failure of VDJ recombination".

Option D

Explanation:

"SCID" is "inherited immune system disorder" which happen due to abnormalities in the response of both T and B cells which are needed for the proper functioning of the immune system. VDJ occurs in genetic recombination occurring in the early or developing stages of lymphocytes. Somatic recombination is also a part of VDJ which results in immunoglobulin's, which is "defining feature" of the immune system and the same which causes severe combined immunodeficiency.
