B. Prokaryotes
C. Slime moulds and protozoa
D. Multicellular and eukaryotes

Answer

**Step-by-Step Solution:**

1. **Understanding the Classification System**: The classification of living organisms is organized into different kingdoms. One of the well-known classification systems was proposed by Robert Whittaker in 1969, which includes five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.

2. **Defining Kingdom Monera**: According to Whittaker's classification, the kingdom Monera is characterized by organisms that are unicellular and prokaryotic. Prokaryotic cells lack a true nucleus and membrane-bound organelles.

3. **Analyzing the Options**:
- **Option 1: Unicellular Eukaryotes** - This is incorrect because Monera consists of prokaryotes, not eukaryotes.
- **Option 2: Prokaryotes** - This is correct as Monera includes unicellular prokaryotic organisms.
- **Option 3: Slime Molds and Protozoa** - This is incorrect because slime molds and protozoa belong to the kingdom Protista, not Monera.
- **Option 4: Multicellular Eukaryotes** - This is also incorrect, as Monera does not include multicellular organisms; it only includes unicellular organisms.

4. **Conclusion**: The only correct option that describes what the kingdom Monera includes is **Option 2: Prokaryotes**.

**Final Answer**: The kingdom Monera includes **prokaryotes**.
