Which of the following is not the characteristic of growth of an organism?

Options

A. It is an irreversible permanent increase in size of an organ / its part/ an individual cell
B. It is accompanied by metabolic processes
C. It is quantitative and intrinsic
D. None of the above

Answer

To solve the question "Which of the following is not the characteristic of growth of an organism?", we need to analyze the given options and determine which one does not align with the characteristics of growth in organisms.

### Step-by-Step Solution:

1. **Understand the Definition of Growth**:
- Growth in organisms is defined as an irreversible and permanent increase in size, which can occur at the level of the whole organism, its organs, or individual cells.

2. **Analyze Each Option**:
- **Option 1**: "It is an irreversible, permanent increase in size of an organ, its part and individual cells."
- This statement is true as growth is indeed irreversible and permanent.

- **Option 2**: "It is occupied by metabolic process."
- This statement is also true. Growth involves metabolic processes that contribute to the increase in size and mass of the organism.

- **Option 3**: "It is Quantitative and Intrinsic."
- This statement is true as well. Growth can be measured quantitatively (e.g., in terms of height, weight) and is intrinsic to the organism's biological processes.

3. **Identify the Incorrect Option**:
- **Option 4**: "None of the above."
- Since all the previous options (1, 2, and 3) are characteristics of growth, this option implies that there is no incorrect statement among the first three.

4. **Conclusion**:
- Therefore, the correct answer is **Option 4: None of the above**, as all the other options correctly describe characteristics of growth in organisms.

### Final Answer:
**Option 4: None of the above**
