Answer:
The correct option is B) Some of the bacteria are resistant to the antibiotic. They survive and reproduce, keeping Maria sick.
Explanation:
The model above shows that some of the bacterial strains were resistant to the antibiotic while some of them did not have resistant properties. When Maria took the antibiotic, the bacteria which did not have the resistant properties were killed. But the bacteria which were resistant to the antibiotic continued to replicate and multiply in number. This is the reason that Maria was still sick and the antibiotic did not have an effect on her health.
