B. Chlamydomonas and Mushroom were placed together in algae
C. Paramecium and Chlorella were placed in same kingdom
D. Both (A) and (C)

Answer

To solve the question regarding Whittaker's five kingdom classification, we will analyze each statement provided in the options and determine their correctness based on the classification system proposed by R.H. Whittaker.

### Step-by-Step Solution:

1. **Understanding Whittaker's Five Kingdom Classification**:
- Whittaker proposed a classification system that includes five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.
- Monera includes prokaryotic organisms (bacteria).
- Protista includes unicellular eukaryotic organisms.
- Fungi includes heterotrophic organisms with chitin cell walls.
- Plantae includes autotrophic organisms with cellulose cell walls.
- Animalia includes multicellular heterotrophic organisms.

2. **Analyzing the Statements**:
- **Statement A**: "It differentiates between heterotrophic fungi and autotrophic green plants."
- This statement is **correct**. Whittaker's classification does differentiate between fungi (heterotrophic) and plants (autotrophic).

- **Statement B**: "Chlamydomonas and mushrooms were placed together in algae."
- This statement is **incorrect**. Chlamydomonas is a green alga and is classified under Protista, while mushrooms belong to the Fungi kingdom. They are not placed together.

- **Statement C**: "Paramecium and cholera were placed in the same kingdom."
- This statement is **correct**. Both Paramecium (a protozoan) and the bacterium that causes cholera (Vibrio cholerae) are classified under the Protista kingdom.

3. **Conclusion**:
- From the analysis, we find that statements A and C are correct while statement B is incorrect.
- Therefore, the correct option regarding Whittaker's five kingdom classification is option 4: "both A and C".

### Final Answer:
The correct option regarding Whittaker's five kingdom classification is **option 4: both A and C**.
