b. using DNA fingerprinting.

c. by looking for overlapping regions between sequenced DNA fragments.

d. using open reading frames.

is:

a. by sequencing each gene on each chromosome, one at a time.

The human genome was sequenced not directly but by breaking these genomes into smaller ones and sequencing each chromosome

a. by sequencing each gene on each chromosome, one at a time.
