Options

A. `i-a,ii-b,iii-c,iv-d`
B. `iii-d,iv-c,i-b,ii-a`
C. `ii-a,iii-b,ii-d,iv-c`
D. `iv-c,ii-a,iii-b,iv-d`

Answer

To solve the matching question regarding the classification of pteridophytes, we will go through each item in Column I and match it with the correct item in Column II based on their classifications.

### Step-by-Step Solution:

1. **Identify the Classes of Pteridophytes**:
- Pteridophytes are classified into four main classes:
- Psilopsida
- Lycopsida
- Sphenopsida
- Pteropsida

2. **Match Each Organism with Its Class**:
- **(a) Selaginella**:
- Selaginella belongs to the class **Lycopsida**.
- **(b) Equisetum**:
- Equisetum belongs to the class **Sphenopsida**.
- **(c) Adiantum**:
- Adiantum belongs to the class **Pteropsida**.
- **(d) Dryopteris**:
- Dryopteris also belongs to the class **Pteropsida**.

3. **Compile the Matches**:
- Based on the classifications:
- (a) Selaginella → (ii) Lycopsida
- (b) Equisetum → (iii) Sphenopsida
- (c) Adiantum → (iv) Pteropsida
- (d) Dryopteris → (iv) Pteropsida

4. **Final Matching**:
- The correct combinations are:
- (a) Selaginella → (ii) Lycopsida
- (b) Equisetum → (iii) Sphenopsida
- (c) Adiantum → (iv) Pteropsida
- (d) Dryopteris → (iv) Pteropsida

5. **Select the Correct Option**:
- From the analysis, the correct combination is found in option 4.
