D. Caphalothorax involves

Answer

To solve the question regarding the common feature in silverfish, scorpion, dragonfly, and prawn, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organisms**:
- We have four organisms: silverfish, scorpion, dragonfly, and prawn.

2. **Classify the Organisms**:
- All four organisms belong to the phylum **Arthropoda**. This is important because members of this phylum share certain characteristics.

3. **Analyze the Options**:
- **Option A**: Three pairs of legs in segmented body.
- This is incorrect because not all of these organisms have three pairs of legs. For example, silverfish have more than three pairs.
- **Option B**: Chitinous cuticle and two pairs of antennae.
- This is also incorrect because not all of them have two pairs of antennae (e.g., scorpions do not have antennae).
- **Option C**: Jointed appendages and chitinous exoskeleton.
- This is correct. All these organisms have jointed appendages and a chitinous exoskeleton.
- **Option D**: Cephalothorax is involved.
- This is incorrect because not all of them have a cephalothorax (e.g., silverfish do not have a cephalothorax).

4. **Conclusion**:
- The common feature among silverfish, scorpion, dragonfly, and prawn is **jointed appendages and chitinous exoskeleton**. Therefore, the answer is **Option C**.

### Final Answer:
**C. Jointed appendages and chitinous exoskeleton.**
