Match the columns -I and Column -II and choose the correct combination the options given
`{:("","ColumnI","","Column-II"),(A,"Echinus",i,"Brittle star"),(B,"Cucumaria",ii,"star fish"),(C,"Antedon",iii,"Sea urchin"),(D,"Ophiura",iv,"Sea cucumber"),(E,"Asterias",vi,"Sea lily"):}`

Options

A. a-4,b-3,c-5,d-2,e-1
B. a-3,b-4,c-5,d-1,e-2
C. a-3,b-4,c-5,d-2,e-1
D. a-3,b-5,c-4,d-1,e-2

Answer

To solve the problem of matching the columns, we will follow these steps:

### Step 1: Identify the Organisms in Column I
We have the following organisms in Column I:
- A: Echinus
- B: Cucumaria
- C: Antedon
- D: Ophiura
- E: Asterias

### Step 2: Identify the Corresponding Names in Column II
We have the following names in Column II:
- i: Brittle star
- ii: Starfish
- iii: Sea urchin
- iv: Sea cucumber
- vi: Sea lily

### Step 3: Match Each Organism with its Common Name
1. **Echinus (A)**: This is commonly known as the **Sea urchin** (iii).
2. **Cucumaria (B)**: This is commonly known as the **Sea cucumber** (iv).
3. **Antedon (C)**: This is commonly known as the **Sea lily** (vi).
4. **Ophiura (D)**: This is commonly known as the **Brittle star** (i).
5. **Asterias (E)**: This is commonly known as the **Starfish** (ii).

### Step 4: Write Down the Matches
Now we can summarize the matches:
- A (Echinus) → iii (Sea urchin)
- B (Cucumaria) → iv (Sea cucumber)
- C (Antedon) → vi (Sea lily)
- D (Ophiura) → i (Brittle star)
- E (Asterias) → ii (Starfish)

### Step 5: Choose the Correct Combination
From the matches, we can see the correct combinations:
- A → iii
- B → iv
- C → vi
- D → i
- E → ii

Now, looking at the options provided, the correct combination corresponds to option B.

### Final Answer
The correct combination is **Option B**.
