Following are the two statements regarding the origin of life :
A.`" "` The earliest organisms that appeared on the earth were non-green and presumably anaerobes.
B.`" "` The first autotrophic organisms were the chemoautotrophs that never relesed oxygen.
Of the above statements which one of the following options is correct ?

Options

A. (ii) is correct but (i) is false
B. Both (i) and (ii) are correct
C. Both (i) and (ii) are false
D. (i) is correct but (ii) is false

Answer

To determine the correctness of the two statements regarding the origin of life, we can analyze each statement step by step.

### Step-by-Step Solution:

1. **Analyze Statement A**:
- The statement claims that "the earliest organisms that appeared on the earth were non-green and presumably anaerobes."
- **Evaluation**:
- Early life forms are believed to have been simple, non-green organisms.
- These organisms likely did not perform photosynthesis and were anaerobic, meaning they did not require oxygen for survival.
- **Conclusion**: This statement is **true**.

2. **Analyze Statement B**:
- The statement claims that "the first autotrophic organisms were the chemoautotrophs that never released oxygen."
- **Evaluation**:
- Chemoautotrophs are organisms that obtain energy by oxidizing inorganic substances and do not rely on sunlight for energy.
- During the early stages of Earth's history, the atmosphere lacked free oxygen, and these organisms would not have released oxygen as a byproduct of their metabolic processes.
- **Conclusion**: This statement is also **true**.

3. **Final Assessment**:
- Both statements A and B are correct based on our analysis.
- Therefore, the correct option is that both statements are true.
