Researchers are designing several experiments to test the ability of Salmonella bacteria to develop antibiotic resistance. A culture of Salmonella bacteria is exposed to the same concentrations (200 mg/L) of an antibiotic for four days. The table shows the number of isolated resistant bacteria over a four-day period. Which of the following statements best explains these results?
A - The bacteria were not affected by the antibiotic.
B - After being exposed to the antibiotic, the bacteria altered their DNA.
C - A new species of bacteria emerged after the antibiotics were introduced.
D - Random mutations led some bacteria to be resistant and, over time, they increased in the population.
