Match the following and select the correct option from the codes given below .
`{:("Column-I","Column-II",),((a)"Physalia",(i)"Sea anemone",),((b)"Meandrina",(ii)"Brain coral",),((c )"Gorgonia",(iii)"Sea fan",),((d)"Adamsia",(iv)"Portiguese man -of -war",):}`

Options

A. `{:((a)(b)(c )(d)),((iii)(ii)(i)(iv)):}`
B. `{:((a)(b)(c)(d)),((iv)(ii)(iii)(i)):}`
C. `{:((a)(b)(c )(d)),((ii)(iii)(i)(iv)):}`
D. `{:((a)(b)(c )(d)),((ii)(iii)(i)(iv)):}`

Answer

To solve the matching question, we need to pair the organisms from Column-I with their corresponding common names in Column-II. Let's go through each option step by step:

### Step-by-Step Solution:

1. **Identify Organism A: Physalia**
- Physalia is commonly known as the **Portuguese man-of-war**.
- Therefore, we match **A (Physalia)** with **(iv) Portuguese man-of-war**.

2. **Identify Organism B: Meandrina**
- Meandrina is known as the **brain coral** due to its grooved surfaces that resemble the convolutions of a brain.
- Thus, we match **B (Meandrina)** with **(ii) Brain coral**.

3. **Identify Organism C: Gorgonia**
- Gorgonia is commonly referred to as the **sea fan** because of its fan-like appearance.
- Hence, we match **C (Gorgonia)** with **(iii) Sea fan**.

4. **Identify Organism D: Adamsia**
- Adamsia is known as the **sea anemone**.
- Therefore, we match **D (Adamsia)** with **(i) Sea anemone**.

### Final Matches:
- A → iv (Portuguese man-of-war)
- B → ii (Brain coral)
- C → iii (Sea fan)
- D → i (Sea anemone)

### Summary of Matches:
- A (Physalia) → iv (Portuguese man-of-war)
- B (Meandrina) → ii (Brain coral)
- C (Gorgonia) → iii (Sea fan)
- D (Adamsia) → i (Sea anemone)

### Correct Option:
The correct order of matches is:
- A4, B2, C3, D1
