Match the columns l and ll,and choose the CORRECT combination from the options given .
`{:("column I","Column II Approx. Number of species"),("a. Beetles","1.20,000"),("b. Ants","2. 28,000"),("c. Orchids","3. 30,000"),("d. Fishes","4.3,00,000"):}`

Options

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

Answer

To solve the problem of matching the species in Column I with their approximate number in Column II, we will analyze each item in Column I and find the corresponding number from Column II.

### Step-by-Step Solution:

1. **Identify the species in Column I:**
- a. Beetles
- b. Ants
- c. Orchids
- d. Fishes

2. **Identify the approximate number of species in Column II:**
- 1. 20,000
- 2. 28,000
- 3. 30,000
- 4. 3,00,000

3. **Match each species with its approximate number:**
- **Beetles:** It is known that beetles are one of the most diverse groups of insects, with around **3,00,000 species**. So, we match:
- a. Beetles → 4. 3,00,000

- **Ants:** Ants have approximately **20,000 species**. Thus, we match:
- b. Ants → 1. 20,000

- **Orchids:** Orchids are a diverse group of flowering plants, with around **30,000 species**. Therefore, we match:
- c. Orchids → 3. 30,000

- **Fishes:** Fishes have a higher diversity, with approximately **28,000 species**. Hence, we match:
- d. Fishes → 2. 28,000

4. **Final Matching:**
- a. Beetles → 4. 3,00,000
- b. Ants → 1. 20,000
- c. Orchids → 3. 30,000
- d. Fishes → 2. 28,000

### Conclusion:
The correct combination is:
- a → 4
- b → 1
- c → 3
- d → 2
