Select the correct statement.

Options

A. Arthropoda is the largest class of kingdom Animalia
B. Closed type of circulatory system is found in annelids.
C. Neophrone belongs to class Reptilia
D. Psittacula is the Natioal bird of India

Answer

To solve the question, we need to evaluate each of the four statements provided and determine which one is correct.

### Step-by-Step Solution:

1. **Evaluate Statement A: "Orthopoda is the largest class of Kingdom Animalia."**
- This statement is incorrect. Orthopoda (more accurately spelled as Arthropoda) is the largest phylum in the Kingdom Animalia, not a class. The largest class within Arthropoda is Insecta.

**Hint:** Remember the hierarchy of biological classification: Phylum > Class.

2. **Evaluate Statement B: "Close type of circulatory system is found in Annelids."**
- This statement is correct. Annelids, such as earthworms, have a closed circulatory system where blood is contained within vessels, allowing for efficient transport of nutrients and gases.

**Hint:** Recall the difference between open and closed circulatory systems: in closed systems, blood is always contained within vessels.

3. **Evaluate Statement C: "Neophron belongs to class Reptilia."**
- This statement is incorrect. Neophron, commonly known as the Egyptian Vulture, belongs to the class Aves (birds), not Reptilia.

**Hint:** Classify organisms based on their characteristics: Neophron is a bird, so it belongs to Aves.

4. **Evaluate Statement D: "Situacula is the national bird of India."**
- This statement is incorrect. The national bird of India is the Peacock (Pavo cristatus), not Situacula (which is not a recognized name for any bird).

**Hint:** Verify national symbols with reliable sources to ensure accuracy.

### Conclusion:
After evaluating all four statements, the only correct statement is **B: Close type of circulatory system is found in Annelids.**

### Final Answer:
B. Close type of circulatory system is found in Annelids.
