- A Klinefelter's syndrome
- B Down's syndrome
- C Turner's syndrome
- D cri du chat syndrome
Answer & Solution
Correct Answer
(A) Klinefelter's syndrome
Step-by-step Solution
Detailed explanation
(A) Klinefelter's syndrome,
Gynaecomastia, which is the development of enlarged breast tissue in males, is a symptom of Klinefelter's syndrome. Klinefelter's syndrome is a genetic condition where males have an extra X chromosome (XXY). This can lead to symptoms such as reduced testosterone levels, small testes, and reduced fertility, along with physical traits like gynaecomastia.
