The correct answer is **B. By cutting and pasting it into a plasmid.**
In genetic engineering, the human insulin gene is introduced into bacteria (such as E. coli) by first isolating the gene and then incorporating it into a plasmid, which is a small, circular piece of DNA that can replicate independently within a bacterial cell. The plasmid acts as a vector to carry the human gene into the bacteria, allowing them to produce insulin.
