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 question, we need to match the organisms in Column I with their approximate number of species in Column II. Let's analyze each organism one by one:

1. **Beetles**:
- Beetles belong to the phylum Arthropoda and are known to have approximately 300,000 species.
- Therefore, we match **Beetles (a)** with **3 (300,000)**.

2. **Ants**:
- Ants also belong to the phylum Arthropoda and have approximately 20,000 species.
- Thus, we match **Ants (b)** with **2 (20,000)**.

3. **Orchids**:
- Orchids are a family of flowering plants and are known to have around 30,000 species.
- Hence, we match **Orchids (c)** with **3 (30,000)**.

4. **Fishes**:
- The total number of fish species is around 28,000.
- Therefore, we match **Fishes (d)** with **1 (28,000)**.

Now, let's summarize the matches:
- a. Beetles → 4. 300,000
- b. Ants → 2. 20,000
- c. Orchids → 3. 30,000
- d. Fishes → 1. 28,000

Thus, the correct combination is:
- a → 4
- b → 2
- c → 3
- d → 1

Now, let's choose the correct option based on the matches we have made.

### Final Matches:
- a. Beetles → 4 (300,000)
- b. Ants → 2 (20,000)
- c. Orchids → 3 (30,000)
- d. Fishes → 1 (28,000)

### Correct Option:
The correct combination is option **D**.
