Match the columns-I with column-II and select the correct answer :-
`{:(" Column-I"," Column-II"),("(A)Pachytene","(i)Bouqute stage"),("(B)Zygotene","(ii)Chiasma visible"),("(C) Diplotene","(iii)Terminalisation"),("(D)Leptotene","(iv) Gene exchange"),("(E)Diakinesis","(v) Synapsis"):}`

Options

A. A-i, B-ii, C-iii, D-iv, E-v
B. A-iv, B-v, C-ii, D-i, E-iii
C. A-iii, B-iv, C-v, D-ii, E-i
D. A-ii, B-iii, C-iv, D-i, E-v

Answer

To solve the matching question between Column-I and Column-II, we will analyze each stage of prophase in meiosis and match it with the correct description.

### Step-by-Step Solution:

1. **Identify the stages of prophase in Column-I:**
- (A) Pachytene
- (B) Zygotene
- (C) Diplotene
- (D) Leptotene
- (E) Diakinesis

2. **Match each stage with the correct description in Column-II:**
- **(A) Pachytene**: This is the third stage of prophase I where homologous chromosomes are fully paired, and gene exchange occurs. Therefore, it matches with (iv) Gene exchange.

- **(B) Zygotene**: In this stage, homologous chromosomes begin to pair up through a process called synapsis. Thus, it matches with (v) Synapsis.

- **(C) Diplotene**: During this stage, the paired chromosomes start to separate, and chiasmata (the points where crossing over occurs) become visible. Hence, it matches with (ii) Chiasma visible.

- **(D) Leptotene**: In this initial stage, chromosomes condense and the telomeres attach to the nuclear envelope, forming a bouquet-like structure. Therefore, it matches with (i) Bouquet stage.

- **(E) Diakinesis**: This is the final stage of prophase I where the homologous chromosomes are fully separated and ready for metaphase. It is also referred to as terminalization. Thus, it matches with (iii) Terminalisation.

3. **Final Matching:**
- (A) Pachytene → (iv) Gene exchange
- (B) Zygotene → (v) Synapsis
- (C) Diplotene → (ii) Chiasma visible
- (D) Leptotene → (i) Bouquet stage
- (E) Diakinesis → (iii) Terminalisation

### Conclusion:
The correct matches are:
- (A) → (iv)
- (B) → (v)
- (C) → (ii)
- (D) → (i)
- (E) → (iii)
