Answer

To determine the classification of Millipedes (Julus) and Centipedes (Scolopendra), we need to analyze the options provided:

1. **Understanding the Options**:
- **A. Arachnida**: This class includes spiders, scorpions, and ticks, which are not related to millipedes and centipedes.
- **B. Myriapoda**: This class includes both millipedes and centipedes, which are characterized by having many legs.
- **C. Scaphopoda**: This class consists of marine mollusks, such as tusk shells, which are unrelated to the organisms in question.
- **D. Pelecypoda**: This class includes bivalve mollusks like clams and oysters, which also do not include millipedes or centipedes.

2. **Identifying the Correct Class**:
- Since both millipedes and centipedes are known for their many legs and belong to the same taxonomic group, we can conclude that they fall under the class **Myriapoda**.

3. **Final Answer**:
- Therefore, the correct answer is **B. Myriapoda**.
