In T4 phage, a mutation in the rII locus gives rise to large and round plaques, while wild-type plaques are small and ragged. Ten independent mutants (M1 to M10) in the rII locus were tested in pairwise complementation assays. In general, mutants that fail to complement belong to the same complementation group. The following conclusions were drawn: A. The mutants map to two complementation groups. B. M1 and M10 are mutations in two different genes. C. Each complementation group is represented by 5 mutants. Which one of the following options represents a combination of correct statement(s)?
