Which of these statements about the living state is correct ?

Options

A. Living state is an equilibrium unsteady state to be able to perform work
B. Living state is an equilibrium unsteady state not able to perform work
C. Living state is a non - equilibrium steady state to be able to perform work
D. Living state is a non - equilibrium unsteady state not able to perform work

Answer

To determine which statement about the living state is correct, we need to analyze each option provided.

### Step-by-Step Solution:

1. **Understanding the Living State**: The living state refers to the condition of living organisms, which are characterized by their ability to perform work, maintain homeostasis, and undergo metabolic processes.

2. **Evaluating the First Statement**:
- **Statement**: "Living state is an equilibrium unsteady state to be able to perform work."
- **Analysis**: This statement is incorrect because living systems are not in equilibrium. If they were, they would not be able to perform work. Living organisms continuously exchange energy and matter with their environment to maintain their state.

3. **Evaluating the Second Statement**:
- **Statement**: "Living state is on equilibrium unsteady state, not able to perform work."
- **Analysis**: This statement is also incorrect. While it mentions an unsteady state, it incorrectly states that living organisms cannot perform work. Living systems are dynamic and require energy input to maintain their functions.

4. **Evaluating the Third Statement**:
- **Statement**: "Living state is a non-equilibrium, steady state to be able to perform work."
- **Analysis**: This statement is correct. Living systems are in a non-equilibrium state, which allows them to perform work. They maintain a steady state through continuous energy input, which is essential for metabolic activities.

5. **Evaluating the Fourth Statement**:
- **Statement**: "Living state is a non-equilibrium, unsteady state, not able to perform work."
- **Analysis**: This statement is incorrect. While it correctly identifies the living state as non-equilibrium, it wrongly states that living organisms cannot perform work. In reality, they are capable of doing so.

### Conclusion:
Based on the analysis, the correct statement about the living state is:
- **Option 3**: "Living state is a non-equilibrium, steady state to be able to perform work."
