Final Answer :
C
Explanation :
The description matches the physical characteristics of Down syndrome. People with Down syndrome have three copies of chromosome 21 instead of the normal two, which causes physical and intellectual disabilities. The extra fold of skin at the corners of the eyes is called an epicanthal fold and is commonly seen in people with Down syndrome. The other options (Turner's syndrome, Klinefelter's syndrome, and hemophilia) do not typically present with these physical characteristics.
