To match List-I with List-II, we need to find the correct association for each item provided:

(A) Genetically engineered Human Insulin - This is produced using recombinant DNA technology and commonly involves the bacterium E. coli.

(B) GM Cotton - This is genetically modified cotton, which typically involves the incorporation of genes from Bacillus thuringiensis (Bt) to produce pest-resistant cotton.

(C) ADA Deficiency - Ada deficiency is often treated using gene therapy.

(D) ELISA - ELISA (Enzyme-Linked Immunosorbent Assay) is a test that uses antigen-antibody interactions to detect the presence of a substance, usually an antigen or antibody, in a liquid sample.

Now let's match them with List-II:

So, the correct answer is:

Option D: A-II, B-IV, C-I, D-III
