Answer

B. A - (iv), B - (i), C - (ii), D - (iii)
Explanation:
Transformation is a procedure through which a piece of DNA is introduced in a host bacterium, the DNA fragments resulting from digestion of DNA by restriction endonucleases can be separated by a technique known as gel electrophoresis, each restriction endonuclease recognises a specific palindromic nucleotide sequence in the DNA called recognition site, and recombinant DNA is composed of DNA from two different sources or organisms.
