The Escherichia coli were killed by the course of antibiotics and new Escherichia coli were introduced to the colon.

It is most probable that the Shigella sonnei shared the gene for ampicillin resistance with the Escherichia coli through transformation.

It is most probable that the Shigella sonnei shared the gene for ampicillin resistance with the Escherichia coli through conjugation.

The Escherichia coli were able to survive the course of antibiotics and acquire the new gene for resistance.

It is most probable that the Shigella sonnei shared the gene for ampicillin resistance with the Escherichia coli through transposons.

It most probable that a random mutation during the course of antibiotic treatment allowed the Escherichia coli cells to become resistant to ampicillin.
