Answer:
C
Explanation:
In the cloning media, not all bacteria will take up the plasmid but some will. Including the antibiotic resistance gene allows the researcher to be able to select the bacteria that take up the plasmid (which are of interest to her because they will now bear the cloned gene). To select these cloned bacteria she puts ampicillin into the medium after some time. The bacteria that took up the plasmid, which also bore the antibiotic resistance gene, will survive and can be reproduced to give more bacteria population with the introduced human gene.
