Which of the following is not a criterian for classification of living organisms?

Options

A. Body design of the organism
B. Ability to produce one's own food
C. Membrane bound nucleus and cell organelles
D. Height of the plant

Explanation

To determine which of the following is not a criterion for the classification of living organisms, we can analyze the given options based on known classification criteria.

### Step-by-Step Solution:

1. **Understand the Criteria for Classification**:
- Living organisms are classified based on several characteristics. Key criteria include:
- Body design (morphology)
- Mode of nutrition (autotrophic vs. heterotrophic)
- Cellular organization (prokaryotic vs. eukaryotic)

2. **Evaluate the Options**:
- Consider each option provided in the question.
- Identify which options align with the established criteria for classification.

3. **Analyze Each Option**:
- **Option 1: Body Design** - This is a valid criterion as it relates to the physical structure of organisms.
- **Option 2: Ability to Produce Food** - This is also a valid criterion as it distinguishes between autotrophs and heterotrophs.
- **Option 3: Bound Nucleus** - This criterion differentiates between prokaryotes (no nucleus) and eukaryotes (with nucleus), making it valid.
- **Option 4: Height of the Plant** - This is not a valid criterion for classification. For example, both small shrubs and large trees can belong to the same group (angiosperms) despite their height differences.

4. **Conclusion**:
- Based on the analysis, the height of the plant is not a criterion for the classification of living organisms. Therefore, the correct answer is **Option 4**.

### Final Answer:
**The height of the plant is not a criterion for classification of living organisms.**
