Solution

The correct option is B 21,000
A gene is a distinct sequence of nucleotides forming part of a chromosome.
Most of the genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. The Human Genome Project estimated that humans have around 21,000 genes.
So, the correct option is '21,000'.
