• A. Klinefelter syndrome
• B. Turner syndrome
• C. Down's syndrome
• D. Both B and C

Answer 1

The correct option is C Down's syndrome

• Klinefelter syndrome is a chromosomal condition that affects male physical and cognitive development.
  
• Turner syndrome is a condition in which a female is partly or completely missing an X chromosome.
  
• Down's syndrome is a condition in which a child is born with an extra copy of their 21st chromosome
  
• Research says that the increased risk of dementia in individuals with Down syndrome may also result from the extra gene. As with all adults, advancing age also increases the chances a person with Down syndrome will develop Alzheimer's disease.
  
• So, the correct answer is' Down's syndrome'.
