I think the correct answer from the choices listed above is option D. Environmental scientists use gel electrophoresis to detect the presence of carp dna in order to track the invasive species silver carp. Environmental detectives are using DNA to track invasive species so this must be the answer.

Environmental scientists use gel electrophoresis to detect the presence of carp DNA. Option D is correct

Natural resource agencies have established surveillance programs which use environmental DNA  for the early detection of bighead carp Hypophthalmichthys nobilis and silver carp Hypophthalmichthys molitrix before they establish populations within the Great Lakes. This molecular monitoring technique must be highly accurate and precise in order to achieve a confident interpretation as well as efficient, both in detection threshold and cost
