Options

A. a(ii), b(i), c(iii), d(iv)
B. a(ii), b(i), c(iv), d(iii)
C. a(i), b(ii), c(iii), d(iv)
D. a(iii), b(ii), c(i), d(iv)

Answer

To solve the matching question, we need to correlate the items in Column I with the appropriate items in Column II based on our understanding of the stages of meiosis. Let's break it down step by step.

### Step-by-Step Solution:

1. **Identify the first item in Column I: "Appearance of recombination nodules"**
- Recombination nodules are structures that appear during the pachytene stage of prophase I of meiosis, where crossing over occurs.
- **Match:** a → (ii) Pachytene

2. **Identify the second item in Column I: "Desynapsis"**
- Desynapsis refers to the separation of homologous chromosomes after crossing over, which occurs during the diplotene stage of prophase I.
- **Match:** b → (i) Diplotene

3. **Identify the third item in Column I: "Disjunction of homologous chromosomes"**
- Disjunction of homologous chromosomes occurs during anaphase I, where homologous chromosomes are pulled apart to opposite poles.
- **Match:** c → (iii) Anaphase-I

4. **Identify the fourth item in Column I: "Centromere division"**
- Centromere division occurs during anaphase II, where sister chromatids are separated as the centromeres split.
- **Match:** d → (iv) Anaphase-II

### Final Matches:
- a → (ii) Pachytene
- b → (i) Diplotene
- c → (iii) Anaphase-I
- d → (iv) Anaphase-II

### Summary of Matches:
- a: Appearance of recombination nodules → (ii) Pachytene
- b: Desynapsis → (i) Diplotene
- c: Disjunction of homologous chromosomes → (iii) Anaphase-I
- d: Centromere division → (iv) Anaphase-II
