Match the animal names listed under Column - I with the locomotor structure given under Column - II and select the correct option from the codes given below .
`{:("Column-I","Column-II"),((a)"Nereis",(i)"Tube feet"),((b )"Pleurobrachia",(ii)"Foot"),((c)"Asterias",(iii)"Parapodia"),((d)"Pila",(iv)"Comb plates"):}`

Options

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

Answer

To solve the matching question between the animals in Column-I and their locomotor structures in Column-II, we will follow these steps:

### Step 1: Identify the Animal Groups
- **Nereis**: This organism belongs to the phylum Annelida.
- **Pleurobrachia**: This organism belongs to the phylum Ctenophora.
- **Asterias**: This organism belongs to the phylum Echinodermata.
- **Pila**: This organism belongs to the phylum Mollusca.

### Step 2: Identify the Locomotor Structures
- **Tube feet**: These are structures used for locomotion in Echinodermata.
- **Foot**: This is a muscular structure used for locomotion in Mollusca.
- **Parapodia**: These are lateral extensions used for locomotion in Annelida.
- **Comb plates**: These are structures used for locomotion in Ctenophora.

### Step 3: Match Animals with Locomotor Structures
1. **Nereis (Annelida)** → **Parapodia (iii)**
- Match: Nereis → Parapodia
2. **Pleurobrachia (Ctenophora)** → **Comb plates (iv)**
- Match: Pleurobrachia → Comb plates
3. **Asterias (Echinodermata)** → **Tube feet (i)**
- Match: Asterias → Tube feet
4. **Pila (Mollusca)** → **Foot (ii)**
- Match: Pila → Foot

### Step 4: Compile the Matches
- (a) Nereis → (iii) Parapodia
- (b) Pleurobrachia → (iv) Comb plates
- (c) Asterias → (i) Tube feet
- (d) Pila → (ii) Foot

### Step 5: Select the Correct Option
Based on the matches:
- A → iii
- B → iv
- C → i
- D → ii

The correct option from the codes given would be:
- (a) - (iii)
- (b) - (iv)
- (c) - (i)
- (d) - (ii)

Thus, the final answer is the option that corresponds to these matches.
