One way that antibiotic resistant strains of bacteria arise is that patients do not follow the instructions for taking the drug.In a typical scenario,a drug may be prescribed for a week,but the patient may stop taking it after 2 to 3 days if they start to feel better.Then when the infection flares up again,they take the rest of their dose.Why would this scenario lead to drug resistance?
A) The first round of treatment gives the bacteria a chance to learn how to metabolize the drug.
B) The first round of treatment does not kill the most resistant bacteria, which then increase in number.
C) The first round of treatment suppresses the immune system, making the patient more susceptible to other infections.
D) A patient begins to develop resistance to the drug.
E) The body clears the drug faster, once it is exposed a second time.
