Options

A. Chitinous exoskelton
B. Metameric sementation
C. Parapodia
D. Jointed appendages

Answer

To determine which feature is not present in the phylum Arthropoda, we will analyze the options provided:

1. **Cutaneous Exoskeleton**:
- Arthropods possess a tough exoskeleton made primarily of chitin. This exoskeleton provides protection and support. Therefore, this feature is present in Arthropoda.

2. **Metameric Segmentation**:
- Metameric segmentation refers to the repetition of body segments and is a characteristic of both Annelida and Arthropoda. Thus, this feature is also present in Arthropoda.

3. **Parapodia**:
- Parapodia are unjointed appendages found in the phylum Annelida, such as in earthworms. Arthropods, on the other hand, have jointed appendages. Therefore, parapodia are not a characteristic of Arthropoda.

Based on the analysis, the feature that is not present in the phylum Arthropoda is **Parapodia**.

### Final Answer:
The feature that is not present in the phylum Arthropoda is **Parapodia**.
