[B] Species that appear the same but show up a difference when their DNA is examined.

Answer: B
Notes:

A study conducted by researchers from Wildlife Institute of India, Dehradun, on amphibians in the central Indian Panna Tiger Reserve has come up with a list of five species hitherto un-documented in this region.  

The researchers, apart from compiling an entire amphibian inventory of this region, have recorded a call library of eleven species and also have obtained molecular confirmation (through DNA) of the cryptic species – a term used to refer to species that appear the same but show up a difference when their DNA is examined.
