Match column I with colimn II and select the correct option from the given codes
`{:(,"Column I",,"Column II"),("A.","Autosomal recessive trait","(i)","Down's syndrome or monogolism"),("B.","Sex-linked rec essive trait","(ii)","Pheylketonuria"),("C.",underset("to autosomal recessive trait")"Metabolic erorr lined","(iii)","Haemophilia"),("D.","Additional 22st chromosome anaemia","(iv)","Sickle cell"):}`

Options

A. A-(ii),B-(i),C-(iv),D-(iii)
B. A-(iv),B-(i),C-(ii),D-(iii)
C. A-(iv),B-(iii),C-(ii),D-(i)
D. A-(iii),B-(iv),C-(i),D-(ii)

Answer

To solve the question of matching Column I with Column II, we will analyze each item in Column I and find the corresponding item in Column II based on the descriptions provided.

### Step-by-Step Solution:

1. **Identify the Traits in Column I**:
- A. Autosomal recessive trait
- B. Sex-linked recessive trait
- C. Metabolic error linked
- D. Additional 22nd chromosome

2. **Match A (Autosomal recessive trait)**:
- Autosomal recessive traits are inherited through autosomes and require two copies of the recessive allele to express the trait.
- Example: Sickle cell anemia is an autosomal recessive disorder.
- **Match**: A → (iv) Sickle cell

3. **Match B (Sex-linked recessive trait)**:
- Sex-linked recessive traits are associated with genes located on the sex chromosomes (X or Y).
- Example: Hemophilia is a well-known sex-linked recessive disorder.
- **Match**: B → (iii) Hemophilia

4. **Match C (Metabolic error linked)**:
- Metabolic errors are typically due to deficiencies in enzymes that lead to the accumulation of substances in the body.
- Example: Phenylketonuria is a metabolic disorder caused by the inability to metabolize phenylalanine.
- **Match**: C → (ii) Phenylketonuria

5. **Match D (Additional 22nd chromosome)**:
- An additional chromosome can lead to genetic disorders. Down syndrome is caused by an extra copy of chromosome 21 (not 22, but this is likely a typographical error in the question).
- **Match**: D → (i) Down's syndrome

6. **Final Matching Summary**:
- A → (iv) Sickle cell
- B → (iii) Hemophilia
- C → (ii) Phenylketonuria
- D → (i) Down's syndrome

### Final Answer:
The correct matches are:
- A → (iv)
- B → (iii)
- C → (ii)
- D → (i)
