Solution

The correct option is B DNA probes
DNA probes are stretches of single-stranded DNA used to detect the presence of complementary nucleotide sequences (target sequences) by hybridization. Genomic library comprises large number of genes in the form of different nucleotide sequences of DNA fragments and they can be selected with the help of DNA probes.
So, the correct option 'DNA probes'.
