Hint: Turner syndrome is a disease that arises due to chromosomal abnormalities and is seen in females. In this disease, the development of sexual features is hindered and such females are not fertile.

Complete answer: Turner syndrome is a type of chromosomal abnormality seen in the case of females.
1. Females affected with this syndrome are said to be sterile and they have only one X chromosome in their DNA rather than two X chromosomes.
2. Such women have manly appearances and show decreased development of reproductive structures, they have short stature, and puberty us usually delayed.
3. This type of chromosomal abnormality is also known as the monosomy of the X chromosome and the genotype of such females is represented as 44A+XO, where A represents the Autosomes.

Hence, the correct option is (C), 44A+XO.

Note: Females suffering from Turner syndrome are not fertile and in these females development of sexual organs and features is hindered. All these abnormalities are present because of the absence of one X chromosome.
