________ are bacteria that can grow on minimal medium and are assumed to be wild type

The following figure demonstrates the genotypic adaptive landscape of bacteria in me-dia lacking antibiotics
As with all adaptive landscapes, the height of the bars associated with a genotype indicate the fitness of that genotype. The R allele confers resistance to antibiotics, and the C allele compensates for the loss of fitness that the R allele confers in the absence of antibiotics. The rc haplotype lacks both compensation and resistance. Based on this landscape, why are resistance and compensation unlikely to be lost even in the absence of antibi-otics? a. A lack of mutation will prevent the haplotypes from changing. b. Epistasis will maintain haplotype frequencies. c. Haplotype frequencies do not change in Hardy–Weinberg populations. d. RC populations are stuck on a local maxima. e. Bacteria evolve slowly.
