Correct answer · Option A
A-III, B-IV, C-I, D-II
Explanation
Down's syndrome is caused by trisomy of chromosome 21 (A-III). \( \alpha \)-thalassemia is controlled by genes on chromosome 16 (B-IV). \( \beta \)-thalassemia is controlled by a gene on chromosome 11 (C-I). Klinefelter's syndrome is due to an additional X chromosome (D-II).
