Match the Columns I and II, and choose the correct combination from the options given.
`{:("Column-I","Column-II"),("Taxonomis group","Threat of extinction"),((a)"Birds",(1)"12 per cent"),((b)"Amphibians",(2)"23 percent"),((c)"Mammals",(3)"31 per cent"),((d)"Gymnosperms",(4)"32 pert cent"):}`

Options

A. a-1,6-2,0-3,d-4
B. a-2,6-1,0-4,d-3
C. a-1,6-4,c-2,d-3
D. a-1,6-3,0-2,d-4

Answer

To solve the problem of matching the taxonomic groups with their respective threats of extinction, we can follow these steps:

### Step 1: Understand the Columns
We have two columns:
- **Column I**: Taxonomic groups (Birds, Amphibians, Mammals, Gymnosperms)
- **Column II**: Percentage of threat of extinction (12%, 23%, 31%, 32%)

### Step 2: Match Each Taxonomic Group with its Threat Level
1. **Birds**: According to the information, birds are threatened by extinction at a rate of **12%**.
- Match: Birds (a) → 12% (1)

2. **Amphibians**: Amphibians are reported to have a **32%** threat of extinction.
- Match: Amphibians (b) → 32% (4)

3. **Mammals**: Mammals are facing a **23%** threat of extinction.
- Match: Mammals (c) → 23% (2)

4. **Gymnosperms**: Gymnosperms have a **31%** threat of extinction.
- Match: Gymnosperms (d) → 31% (3)

### Step 3: Compile the Matches
Based on the above matches, we can summarize:
- (a) Birds → (1) 12%
- (b) Amphibians → (4) 32%
- (c) Mammals → (2) 23%
- (d) Gymnosperms → (3) 31%

### Step 4: Choose the Correct Combination
Now, we can look for the option that represents these matches correctly. The correct combination based on our matching is:
- (a) → (1)
- (b) → (4)
- (c) → (2)
- (d) → (3)

### Final Answer
The correct option that matches these pairs is **Option C**.
