Final Answer :
C
Explanation :
An XO genotype typically refers to a person who has only one X chromosome, which is characteristic of Turner syndrome. Down syndrome is caused by an extra copy of chromosome 21, cri du chat syndrome is caused by a deletion on the short arm of chromosome 5, Klinefelter syndrome is characterized by an extra X chromosome in males (XXY), and a poly-X state refers to a person who has extra X chromosomes but is not necessarily limited to only having one X chromosome as in the case of XO.
