Which of the following is the correct expression of the "central dogma" ?

Read the passage carefully and answer the given questions.
DNA Fingerprinting Polymorphism in DNA sequence is the basis of genetic mapping of the human genome as well as of DNA fingerprinting. DNA fingerprinting involves identification of differences in some specific regions in the DNA sequence called repetitive DNA. It works on the principle of polymorphisms in DNA sequences. The repetitive DNA are separated from bulk genomic DNA. The bulk DNA forms a major peak and the other small peaks are referred to as satellite DNA. These repetitive/satellite DNA sequences show a high degree of polymorphisms and form the basis of DNA fingerprinting.
DNA fingerprinting is meant for:

Mammals are able to survive in Antarctica or in the Sahara desert as they are

Arrange the following steps of DNA fingerprinting in correct sequence :
(A) Separation of DNA fragments by electrophoresis and transfer to nitrocellulose membrane
(B) Autoradiography based detection of hybridised DNA
(C) Hybridisation using labelled VNTR probe
(D) Isolation of DNA and digestion by restriction endonuclease
