Answer:
A,C, D
Explanation:
Bacteria that acquired a mutation that conferred drug- resistance had a growth advantage over non-resistant bacteria.
Between time points C and D, drug-resistant bacteria were reproducing faster than non-drug resistant bacteria were dying.
The few drug-resistant bacteria in the population reproduced, quickly leading to a large drug- resistant population.
There is no indication that a second antibiotic was used, so it is not possible to assume a second drug-resistance mutation occurred. There is also no indication that antibiotics were discontinued.
