Answer

To fill in the blanks in the table provided, we need to identify the correct excretory organs, circulatory systems, and respiratory organs for the given phyla/classes. Let's go through each part step by step.

### Step 1: Identify the Excretory Organ for Arthropoda (A)
- The excretory organ for Arthropoda is **Malpighian tubules**.
- Therefore, we fill in **A = Malpighian tubules**.

### Step 2: Identify the Circulatory System for Arthropoda (B)
- The circulatory system in Arthropoda is **open**.
- Therefore, we fill in **B = Open**.

### Step 3: Identify the Phylum/Class for Nephridia (C)
- The excretory organ **Nephridia** is characteristic of the phylum **Annelida**.
- Therefore, we fill in **C = Annelida**.

### Step 4: Identify the Circulatory System for Annelida
- The circulatory system in Annelida is **closed**.
- Therefore, we fill in the circulatory system for C as **Closed**.

### Step 5: Identify the Respiratory Organ for Annelida
- The respiratory organ for Annelida is typically **Skin**.
- Therefore, we fill in the respiratory organ for C as **Skin**.

### Step 6: Identify the Excretory Organ for D (Metanephridia)
- The excretory organ **Metanephridia** is found in the phylum **Mollusca**.
- Therefore, we fill in **D = Mollusca**.

### Step 7: Identify the Circulatory System for Mollusca
- The circulatory system in Mollusca is generally **open**.
- Therefore, we fill in the circulatory system for D as **Open**.

### Step 8: Identify the Respiratory Organ for Mollusca (E)
- The respiratory organ for Mollusca is **Gills** (specifically feather-like gills).
- Therefore, we fill in **E = Gills**.

### Final Table:
| Phylum/Class | Excretory Organ | Circulatory System | Respiratory Organ |
|--------------|----------------------|--------------------|----------------------------|
| Arthropoda | Malpighian tubules | Open | Lungs/Gills/Tracheal system|
| Annelida | Nephridia | Closed | Skin |
| Mollusca | Metanephridia | Open | Gills |

### Summary of Answers:
- A = Malpighian tubules
- B = Open
- C = Annelida
- D = Mollusca
- E = Gills
