After 1 year of widely prescribed use,reports surface that bacterial infections disappear for up to 2 weeks after taking the prescribed antibiotic but then reappear,sometimes worse than the first time.Which of the following explanations might the FDA use to defend their choice of antibiotic to treat the infection?
A)Patients are not taking the antibiotic for the length of time prescribed and so selection for resistant bacteria that can survive a limited course of antibiotic is occurring.
B)Stabilizing selection over the year has allowed for the bacteria to remain at a high level in patients' bodies.
C)Patients' bodies are evolving over the year to create environments that are friendly to the growth of the bacteria.
D)Sexual dimorphism allowed for larger bacteria cells to outcompete smaller ones,therefore enabling larger bacteria cells to continue to multiply.

The development of antibiotic-resistant bacteria is a well-known phenomenon that occurs when antibiotics are not taken for the full course of treatment. This allows a subset of bacteria with mutations that make them resistant to the antibiotic to survive and reproduce, leading to a population of antibiotic-resistant bacteria that can be difficult or impossible to treat. The FDA may argue that patients are not taking the antibiotic for the full course of treatment, selecting for resistant bacteria that survive the initial treatment and then cause recurrent infections.
