• Thalassemia → Autosomal recessive disorder → A-IV
• Turner’s Syndrome → $44 + XO$ chromosomes → B-III
• Klinefelter’s Syndrome → $44 + XXY$ chromosomes → C-I
• Down’s Syndrome → $45 + XX$ (Trisomy 21) → D-II

Step 2: Write correct matching.
\[ A\text{-IV},\quad B\text{-III},\quad C\text{-I},\quad D\text{-II} \]

Step 3: Final conclusion.
Thus, the correct option is: \[ (A) \]
