    Answer: Option D) Males have two different chromosomes.

    Explanation:

    The human males have two different chromosomes known as the XY - chromosome. Hence, a human male child receives a Y chromosome from his father with XY, and a X chromosome from his mother with XX.

    Females, on the other hand have similar chromosomes (XX-chromosome), each X received from each parent.

    Thus, the XY-chromosome in human males make for two different chromosomes.
