B)when you have a mutant allele of a gene that is dominant to wild-type alleles.

Deletions are most useful for gene mapping when you have a mutant allele of a gene that is recessive to normal alleles and amorphic. This is because deletions can uncover recessive alleles by removing the corresponding wild-type allele on the homologous chromosome, allowing the phenotype of the recessive allele to be expressed and facilitating the mapping of the gene's location.
