Options

A. (ii),(iii),(iv) and (v)
B. (ii) and (v)
C. (i),(ii) and (v)
D. (i),(ii),(iv) and (v)

Answer

To determine which of the statements regarding animal classification are correct, we will analyze each statement one by one based on the characteristics of the respective phyla.

### Step-by-Step Solution:

1. **Understanding Diploblastic and Triploblastic:**
- **Diploblastic:** Animals that have two germ layers (ectoderm and endoderm). The phyla that are diploblastic include **Poriferans** (sponges) and **Coelenterates** (cnidarians like jellyfish and corals).
- **Triploblastic:** Animals that have three germ layers (ectoderm, endoderm, and mesoderm). The phyla that are triploblastic include **Platyhelminthes** (flatworms) to **Chordates** (vertebrates).

**Conclusion:** Statements (i) and (ii) are correct.

2. **Understanding Coelom Types:**
- **Acoelomate:** Animals that do not have a body cavity (coelom). This includes **Poriferans**, **Coelenterates**, and **Platyhelminthes**.
- **Pseudocoelomate:** Animals that have a false coelom. This includes **Aschelminthes** (roundworms).
- **Eucoelomate:** Animals that have a true coelom. This includes **Annelids** to **Chordates**.

**Conclusion:** Statement (iii) is correct because it includes Poriferans, Coelenterates, and Platyhelminthes as acoelomates. Statement (iv) is correct as it correctly identifies Aschelminthes as pseudocoelomates. Statement (v) is also correct as it correctly identifies Annelids to Chordates as eucoelomates.

3. **Final Evaluation of Statements:**
- (i) "Diploblastic" - Correct (Poriferans, Coelenterates)
- (ii) "Triploblastic" - Correct (Platyhelminthes to Chordates)
- (iii) "Acoelomate" - Correct (Poriferans, Coelenterates, Platyhelminthes)
- (iv) "Pseudocoelomate" - Correct (Aschelminthes/Roundworms)
- (v) "Eucoelomate" - Correct (Annelids to Chordates)

### Conclusion:
All statements except for the incorrect classification of Porifera as acoelomates are correct. Therefore, the correct statements are (ii), (iii), (iv), and (v).

### Correct Answer:
The correct statements are (ii), (iii), (iv), and (v).
