B. Lichen is a composite organism formed from the symbiotic association of an algae and a protozoan
C. Yeast used in making bread and beer is a fungus
D. Nostoc and Anabaena are examples of protists

Answer

To determine which of the provided statements is correct, we will analyze each statement step by step.

### Step-by-Step Solution:

1. **Statement 1: Paramecium and Plasmodium belong to the same kingdom as that of Penicillium.**
- **Analysis:** Paramecium and Plasmodium are both classified under the kingdom Protista. Penicillium, on the other hand, is a fungus and belongs to the kingdom Fungi. Therefore, this statement is **incorrect**.

2. **Statement 2: Lichen is a composite organism formed from the symbiotic association of an algae and a protozoa.**
- **Analysis:** Lichens are indeed composite organisms, but they are formed from the symbiotic association of algae and fungi, not protozoa. Thus, this statement is also **incorrect**.

3. **Statement 3: Yeast used to make bread and beer is a fungus.**
- **Analysis:** Yeast, specifically Saccharomyces cerevisiae, is a type of fungus used in fermentation processes to make bread and beer. This statement is **correct**.

4. **Statement 4: Nostoc and Anabena are examples of protists.**
- **Analysis:** Nostoc and Anabena are actually examples of cyanobacteria, which belong to the kingdom Monera, not Protista. Therefore, this statement is **incorrect**.

### Conclusion:
The only correct statement among the options provided is **Statement 3: Yeast used to make bread and beer is a fungus.**
