B. False
Bacterial populations show genetic and phenotypic variation (different strains, serotypes, and mutants). Variation arises from mutations, horizontal gene transfer (plasmids, transposons, bacteriophages), and gene regulation differences — for example, Escherichia coli includes harmless gut strains and pathogenic strains like O157:H7.
