Match the columns I and II , and choose the CORRECT combination from the options given.
`{:("Column I","Column II"),("(a)Selaginella","(i) Psilopside"),("(b)Equisetum","(ii) Lycopsida"),("(c)Adiantum","(iii)Sphenopsia"),("(d)Dryopteris","(iv)Pteropsida"):}`

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 between Column I and Column II, we need to identify the correct class for each plant listed in Column I. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the plants in Column I
- (a) Selaginella
- (b) Equisetum
- (c) Adiantum
- (d) Dryopteris

### Step 2: Identify the classes in Column II
- (i) Psilopsida
- (ii) Lycopsida
- (iii) Sphenopsida
- (iv) Pteropsida

### Step 3: Match each plant with its corresponding class
1. **Selaginella**: This plant belongs to the class **Lycopsida**.
- Match: (a) Selaginella → (ii) Lycopsida

2. **Equisetum**: This plant is classified under the class **Sphenopsida**.
- Match: (b) Equisetum → (iii) Sphenopsida

3. **Adiantum**: This plant is a member of the class **Pteropsida**.
- Match: (c) Adiantum → (iv) Pteropsida

4. **Dryopteris**: This plant also belongs to the class **Pteropsida**.
- Match: (d) Dryopteris → (iv) Pteropsida

### Step 4: Compile the matches
Now we can summarize the matches:
- (a) Selaginella → (ii) Lycopsida
- (b) Equisetum → (iii) Sphenopsida
- (c) Adiantum → (iv) Pteropsida
- (d) Dryopteris → (iv) Pteropsida

### Step 5: Choose the correct combination
Based on the matches, the correct combination is:
- (a) Selaginella - (ii) Lycopsida
- (b) Equisetum - (iii) Sphenopsida
- (c) Adiantum - (iv) Pteropsida
- (d) Dryopteris - (iv) Pteropsida

### Final Answer
The correct combination is:
- (a) → (ii)
- (b) → (iii)
- (c) → (iv)
- (d) → (iv)
