Answer»

Correct option is (d) similar to the shotgun approach, but on a smaller scale

The explanation: In this, the chromosomes are INITIALLY MAPPED using the physical mapping strategy. Longer fragments of genomic DNA (100 to 300 kB) are OBTAINED and cloned into a high-capacity bacterial vector called bacterial artificial chromosome (BAC).
