A. Annelids are diploblastic , metamerically segmented , coelomate animals.
B. Their neural system consists of paired ganglia connected by lateral nerves to a single ventral nerve cord .
C. They process longitudinal and circular muscle fibres which help in locomotion .
D Nephridia help them in osmoregulation and excretion.

Options

A. A: False , B: True , C: False , D: True
B. A: False , B: False , C: True , D: True
C. A: True , B: False , C: True , D: False
D. A: False , B: True , C: False , D: True

Answer

To solve the question regarding the statements about phylum Annelida, we will analyze each statement one by one to determine whether they are true or false.

### Step 1: Analyze Statement A
**Statement A:** "Annelids are diploblastic, metamerically segmented, coelomate animals."
- **Analysis:** Annelids are actually triploblastic (not diploblastic), metamerically segmented, and coelomate. Therefore, this statement is **False**.

### Step 2: Analyze Statement B
**Statement B:** "Their neural system consists of paired ganglia connected by lateral nerves to a single ventral nerve cord."
- **Analysis:** This statement accurately describes the nervous system of annelids. They do have paired ganglia and a ventral nerve cord. Thus, this statement is **True**.

### Step 3: Analyze Statement C
**Statement C:** "They possess longitudinal and circular muscle fibers which help in locomotion."
- **Analysis:** Annelids do possess both longitudinal and circular muscle fibers, which are essential for their locomotion. Therefore, this statement is **True**.

### Step 4: Analyze Statement D
**Statement D:** "Nephridia help them in osmoregulation and excretion."
- **Analysis:** This statement is also accurate. Nephridia function as excretory organs in annelids, aiding in osmoregulation and excretion. Thus, this statement is **True**.

### Summary of Findings
- **Statement A:** False
- **Statement B:** True
- **Statement C:** True
- **Statement D:** True

### Conclusion
Based on the analysis, the correct identification of the statements is:
- A: False
- B: True
- C: True
- D: True

### Correct Option
The correct option based on the analysis is that A is false, while B, C, and D are true.
