B Correct answer
Explanation

The non-coding regions of DNA are employed for various important functions like mutation buffer, regulation of transcription, replication and other processes, which make it equally important as the coding region. DNA fingerprinting makes use of VNTRs, which are repeat sequences in the non-coding regions.
