Hello!
The answer to your question is B.
The foreign DNA is integrated into one of the cell’s chromosomes.
If transformation is successful, the DNA will be integrated into one of the cell's chromosomes. Recombinant plasmids are simply taken up by bacterial cells. Plant cells do not naturally take up DNA. Recombinant plasmids are either directly injected into cells or carried into the cell by an infecting bacterium.
