What is the most accurate way to explain the relationship between antibiotics and antibiotic-resistant bacteria?

a. Exposing bacteria to antibiotics causes DNA mutations that confer antibiotic resistance.
b. A population of bacteria evolves antibiotic resistance alleles in order to survive exposure to antibiotics.
c. Bacteria with alleles that confer antibiotic resistance are most likely to survive when exposed to antibiotics.
d. Antibiotics bind to alleles that confer antibiotic susceptibility, causing changes that make the gene pool more resistant.
