Solution

The correct option is B One
In humans, each cell normally contains 23 pairs of chromosomes(total of 46). Twenty-two of these pairs called autosomes, which look alike in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Males have one X and one Y chromosome, while females have two copies of the X chromosome.
