Answer A is correct
A.can take up DNA from their surrounding environment and integrate it into their own chromosomes by recombination.
Bacterial cells that can take up the foreign DNA from the surroundings by a process called transformation are known as competent cells.
Competent cells, designed to take up foreign DNA from the surrounding at a higher efficiency, are routinely used in molecular cloning to propagate and maintain cloned DNA in plasmids.
