Four fruit fly mutants (A, B, C, and D) were studied for their ability to produce a certain eye pigment. The mutants are known to result from point mutations. The following table shows the results of the complementation tests between the mutants:
Gene-mapping information identifies mutations B and D as the flanking markers in this group of genes. Which one of the following could be a possible order of mutations in the region of the chromosome?
