Colour generation in the presence of chromogenic substrate can also be used to distinguish between recombinants and non-recombinants.

A recombinant DNA is introduced within the coding sequence of an enzyme -galactosidase, resulting in the enzyme's deactivation. 

As a result, bacterial colonies containing plasmids show no coloration, but those without plasmids show blue coloration.

Option c is the correct answer.
