Which one of the following is not the basis of five kingdom classification ?

Options

A. Cell type
B. Body organisation
C. Reproduction
D. Reserve food materials

Answer

To determine which option is not a basis of the five kingdom classification proposed by R.H. Whittaker, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Five Kingdom Classification**: R.H. Whittaker proposed a classification system that divides life into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. This classification is based on several criteria.

2. **Identify the Criteria Used**: The main criteria used by Whittaker for classifying organisms include:
- **Cell Type**: Whether the organism is prokaryotic or eukaryotic.
- **Body Organization**: Whether the organism is unicellular or multicellular.
- **Mode of Nutrition**: How the organism obtains its food (autotrophic or heterotrophic).
- **Reproduction**: The methods by which organisms reproduce (asexual or sexual).
- **Phylogenetic Relationship**: The evolutionary relationships among organisms.

3. **Analyze the Options**: The question provides four options:
- Cell Type
- Body Organization
- Reproduction
- Reserve Food Material

4. **Determine the Irrelevant Option**:
- Cell Type, Body Organization, and Reproduction are all included in Whittaker's classification criteria.
- **Reserve Food Material** is not a criterion used in the five kingdom classification.

5. **Conclusion**: Therefore, the option that is not a basis of the five kingdom classification is **Reserve Food Material**.

### Final Answer:
**Reserve Food Material** is not the basis of five kingdom classification.
