Which of the following statements is true according to the concept of biological classification ?

Options

A. Bacteria are heterotrophic saprophytic organisms in the kingdom Monera with a great range of diversity.
B. The heterotrophic prokaryotic , multicellular organisms lacking a cell wall are included kingdom Animalia.
C. Kingdom Fungi includes eukaryotic multicellular heterophic organisms which exhibit both sexual as well as asexual modes of reproduction and have a great range of diversity.
D. Kingdom Plantae includes eukaryotic chlorophyll containing unicellular organisms and a few heterotrophs.

Answer

To solve the question regarding which statement is true according to the concept of biological classification, we will analyze each statement based on the classification system proposed by R. H. Whittaker in 1969.

### Step-by-Step Solution:

1. **Understanding Biological Classification**:
- R. H. Whittaker proposed a five-kingdom classification system which includes:
- Kingdom Monera (prokaryotes)
- Kingdom Protista (unicellular eukaryotes)
- Kingdom Fungi (multicellular heterotrophic organisms)
- Kingdom Plantae (multicellular autotrophic organisms)
- Kingdom Animalia (multicellular heterotrophic organisms)

2. **Analyzing Each Statement**:
- **Statement 1**: "Bacteria are heterotrophic saprophytic organisms in the kingdom Monera with a great range of diversity."
- **Analysis**: This statement is incorrect because bacteria can be autotrophic as well (e.g., cyanobacteria).

- **Statement 2**: "The heterotrophic prokaryotic multicellular organisms lacking a cell wall are included in Animalia."
- **Analysis**: This statement is incorrect because prokaryotic organisms (like bacteria) do not belong to the kingdom Animalia; they belong to Monera.

- **Statement 3**: "Kingdom Fungi includes eukaryotic multicellular heterotrophic organisms which exhibit both sexual as well as asexual modes of reproduction and have a great range of diversity."
- **Analysis**: This statement is correct. Kingdom Fungi consists of eukaryotic multicellular organisms that are heterotrophic and can reproduce both sexually and asexually.

- **Statement 4**: "Kingdom Plantae includes eukaryotic chlorophyll-containing unicellular organisms and a few heterotrophs."
- **Analysis**: This statement is incorrect because kingdom Plantae primarily consists of multicellular autotrophic organisms, not unicellular ones.

3. **Conclusion**:
- The only true statement according to the concept of biological classification is Statement 3 regarding Kingdom Fungi.

### Final Answer:
The true statement according to the concept of biological classification is: "Kingdom Fungi includes eukaryotic multicellular heterotrophic organisms which exhibit both sexual as well as asexual modes of reproduction and have a great range of diversity."
