Answer:
B. Any bacteria that happen to have a gene conferring resistance are more likely to survive and breed.
Explanation:
The antibiotic resistance gene is already present in some of the bacteria. these bacteria get a chance to grow and multiply more often, once the other bacteria have died due to the antibiotic.
Thus, a population of antibiotic resistant bacteria arise.
