Right choice is (b) Southern blotting

Best explanation: Southern blotting is the technique where nucleic acids are first transferred from gel to a nitrocellulose membrane. The membrane is then incubated in a solution of probes (complementary sequences) and then the bound sequences analyzed using autoradiography.
