Solution

The correct option is D 44A+XO
In normal individuals, there is XX chromosome in the females and XY chromosome in the males. In case of Turner's syndrome, there is one chromosome absent. These individuals have only one X chromosome and the other sex chromosome is missing. The genotype of these individuals is 44 A + XO. This may be due to non-disjunction of chromosomes during the gamete formation.
Thus, the correct answer is option C.
