Quizplus · Accepted Answer

The selective agent is the factor that causes a selective advantage for one group of organisms over another, leading to the selection and survival of those with the advantageous trait. In this case, the use of antibiotics is the selective agent, as it kills non-resistant bacteria and allows for the survival and proliferation of antibiotic-resistant bacteria.
