Abiogenesis is

Options

A. Origin of life from non-living organisms
B. Origin of microbes from living organisms
C. Spontaneous
D. Origin of microbes and viruses

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Abiogenesis":**
- The term "abiogenesis" can be broken down into three parts:
- "a" meaning absence or no,
- "bio" meaning life,
- "genesis" meaning formation.
- Therefore, abiogenesis refers to the formation of life from non-living matter.

2. **Analyzing the Options:**
- The options provided are:
1. Origin of life from non-living organisms.
2. Origin of microbes from living organisms.
3. Spontaneous generation.
4. Origin of microbes and viruses.

3. **Evaluating Each Option:**
- **Option 1:** "Origin of life from non-living organisms."
- This aligns perfectly with the definition of abiogenesis. This is the correct answer.
- **Option 2:** "Origin of microbes from living organisms."
- This contradicts the concept of abiogenesis, as it refers to life arising from pre-existing life, not from non-living matter.
- **Option 3:** "Spontaneous generation."
- While spontaneous generation is related to the idea of life arising from non-life, it is not synonymous with abiogenesis. Abiogenesis encompasses a broader concept and is not entirely spontaneous.
- **Option 4:** "Origin of microbes and viruses."
- This option is incorrect as it limits the definition of abiogenesis to just microbes and viruses, whereas abiogenesis refers to the origin of all life forms from non-living matter.

4. **Conclusion:**
- Based on the analysis, the correct answer is that abiogenesis is the origin of life from non-living organisms.

**Final Answer:**
Abiogenesis is the origin of life from non-living organisms.
