The living organisms can be undexceptionally distinguished from the non - living things on the basis of their ability for

Options

A. Interaction with the environment and progressive evolution
B. Reproduction
C. Growth and movement
D. Responsiveness to touch

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for the characteristic that distinguishes living organisms from non-living things without exception. This means we need to identify a feature that is universally applicable to all living organisms.

2. **Analyzing the Options:**
We have four options to evaluate:
- A) Interaction with the environment and progressive evolution
- B) Reproduction
- C) Growth and movement
- D) Responses to touch

3. **Evaluating Each Option:**
- **Option A: Interaction with the environment and progressive evolution**
- This option suggests that living organisms can interact with their environment and evolve over time. This is true for all living organisms, as they must adapt to their surroundings to survive.

- **Option B: Reproduction**
- While reproduction is a characteristic of living organisms, there are exceptions. Some organisms, like certain sterile individuals (e.g., some humans), cannot reproduce but are still considered living.

- **Option C: Growth and movement**
- Growth is often associated with living organisms, but non-living entities like mountains can also grow (e.g., through geological processes). Therefore, this is not exclusive to living organisms.

- **Option D: Responses to touch**
- Many living organisms respond to touch, but not all do. For example, a leaf does not respond to touch, even though it is a living organism. Thus, this is also not a universal characteristic.

4. **Conclusion:**
After evaluating all the options, **Option A: Interaction with the environment and progressive evolution** is the only characteristic that applies to all living organisms without exception. Therefore, this is the correct answer.
