Babout 25%
Cabout 50%
Dless than 2%

Correct answer: D. less than 2%
Only about 1.5% of the human genome's 3.2 billion bp actually code for proteins.
The rest is regulatory sequence, structural elements (telomeres, centromeres), introns and non-coding RNA genes.
One of the surprises of the Human Genome Project.
