Answer» CORRECT option is (d) MINIMAL MEDIA

For explanation I would say: Only prototroph can grow in minimal media. In the Ames test, the mutagenicity of a substance is tested by its ability to convert an auxotroph into a prototroph. THUS to check for mutants, the media must be minimal so that only mutant COLONIES grow.
