3. **Body Organization**: Most protists are unicellular, meaning they consist of a single cell. This is a key characteristic of many members of this kingdom.

4. **Analyzing the Options**:
- Option A: Prokaryotic cell structure - Incorrect, as Protista consists of eukaryotic organisms.
- Option B: Eukaryotic cell structure - Correct, as all protists have eukaryotic cells.
- Option C: Unicellular body - Correct, as many protists are unicellular.
- Option D: Both B and C - Correct, since both statements about eukaryotic cell structure and unicellular body are true.

5. **Conclusion**: The correct answer to the question "Protista includes organisms having" is option D: both B and C.
