Which of the following is correct about non-living objects?

Options

A. Doesn't grow
B. Show intrinsic growth
C. Show extrinsic growth
D. Show both extrinsic and intrinsic growth

Answer

To answer the question "Which of the following is correct about non-living objects?", we need to analyze the options provided and understand the concepts of intrinsic and extrinsic growth.

### Step-by-Step Solution:

1. **Understanding Growth Types**:
- **Intrinsic Growth**: This type of growth is characteristic of living organisms. It involves an increase in size, mass, and number due to cell division. Living organisms grow constantly through this process.
- **Extrinsic Growth**: This type of growth occurs in non-living objects. It involves the accumulation of material from external sources, leading to an increase in size. This growth is reversible.

2. **Analyzing the Options**:
- **Option 1**: "They don't grow" - This is incorrect because non-living objects can show extrinsic growth.
- **Option 2**: "They show intrinsic growth" - This is incorrect as intrinsic growth is specific to living organisms.
- **Option 3**: "They show extrinsic growth" - This is correct because non-living objects can grow through the accumulation of materials from external sources.
- **Option 4**: "They show both extrinsic as well as intrinsic growth" - This is incorrect as non-living objects do not exhibit intrinsic growth.

3. **Conclusion**:
- The correct statement about non-living objects is that they show extrinsic growth.

### Final Answer:
The correct option is: **They show extrinsic growth.**
