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 determine which statement is true according to the concept of biological classification, we need to analyze each provided statement based on the five-kingdom classification proposed by R.H. Whittaker in 1969.

### Step-by-Step Solution:

1. **Understanding the Five Kingdoms**:
- The five kingdoms are:
- **Monera**: Includes all prokaryotic organisms (e.g., bacteria).
- **Protista**: Contains unicellular eukaryotic organisms.
- **Fungi**: Comprises heterotrophic organisms, mostly multicellular, that absorb nutrients.
- **Plantae**: Encompasses multicellular, autotrophic organisms that perform photosynthesis.
- **Animalia**: Consists of multicellular, heterotrophic organisms that consume organic material.

2. **Analyzing the Statements**:
- **Statement 1**: "Bacteria are heterotropic saprophytic organisms in the kingdom Monera with a great range of diversity."
- **Analysis**: This statement is incorrect because not all bacteria are heterotrophic; some, like cyanobacteria, are autotrophic.

- **Statement 2**: "The heterotropic prokaryotic multicellular organisms lacking a cell wall are included in kingdom Animalia."
- **Analysis**: This statement is incorrect. All prokaryotes, including heterotrophic ones, are classified under Monera, not Animalia.

- **Statement 3**: "Kingdom Fungi includes Eukaryotic, Multicellular, Heterotropic organisms."
- **Analysis**: This statement is correct. Fungi are primarily multicellular and heterotrophic, absorbing nutrients from their environment.

- **Statement 4**: "The kingdom Plantae includes eukaryotic chlorophyll-containing unicellular organisms."
- **Analysis**: This statement is incorrect. The Plantae kingdom primarily consists of multicellular organisms, although there are unicellular algae, they are not classified under Plantae.

3. **Conclusion**:
- The only true statement according to the concept of biological classification is **Statement 3**: "Kingdom Fungi includes Eukaryotic, Multicellular, Heterotropic organisms."

### Final Answer:
The correct statement is: **"Kingdom Fungi includes Eukaryotic, Multicellular, Heterotropic organisms."**
