The correct answer is (D) As a positive control to show if there are bighead carp present in the area.

Recently, there has been use of various molecular methods to detect the presence of environmental DNA (eDNA) has become a boon in the surveillance programs that is used to monitor the presence of invasive species in the aquatic system. This technique can detect the presence of nucleic acid in water even if the species are not present in water. It was also used as a positive control to show if there is presence of bighead carp (fish) in that particular area.
