A
for gene therapy
B
to make a particular protein.
C
to clone a specific piece of protein/gene.
D
All of the above.
Explanation: 

Detailed explanation-1: -In recombinant DNA technology, a desired segment of DNA or a gene is made to combine with the DNA’ of an organism where it with multiply and produce its copies. Plasmids and viruses are the most commonly used cloning vectors in recombinant DNA technology.

Detailed explanation-2: -Recombinant DNA technology has been successfully applied to make important proteins used in the treatment of human diseases, such as insulin and growth hormone.

Detailed explanation-3: -Explanation: DNA ligase is used to join two different types of DNA molecules, thus giving rise to a recombinant molecule that can be cloned inside a suitable host to facilitate the gene expression.
