Solution

The correct option is D Selection of recombinants
Selection of recombinants due to inactivation of antibiotics is a cumbersome procedure. Therefore, alternative selectable markers have been developed which differentiate recombinants from non-recombinants on the basis of their ability to produce colour in the presence of a chromogenic substrate, which is referred to as insertional inactivation.
