Theory of a abiogenesis is
(a) Theory of spontaneous creation
(b) Theory of special creation
(c) Cosmozoic theory
(d) Theory of panspermia

Options

A. Theory of spontaneous creation
B. Theory of special creation
C. Cosmozoic theory
D. Theory of panspermia

Answer

To determine which option correctly describes the theory of abiogenesis, we can analyze each option step by step:

### Step-by-Step Solution:

1. **Understanding Abiogenesis**:
- Abiogenesis refers to the process by which life arises naturally from non-living matter, such as simple organic compounds. It suggests that life originated from abiotic (non-living) components.

2. **Analyzing Option (a): Theory of Spontaneous Creation**:
- This theory posits that life can arise spontaneously from non-living matter under suitable conditions. This aligns with the concept of abiogenesis, as it suggests that life emerged from abiotic components without any supernatural intervention.
- **Conclusion**: This option is consistent with the theory of abiogenesis.

3. **Analyzing Option (b): Theory of Special Creation**:
- This theory suggests that life was created by a supernatural entity, such as God. It implies an external force or intervention in the creation of life.
- **Conclusion**: This does not align with the principles of abiogenesis, making it an incorrect option.

4. **Analyzing Option (c): Cosmozoic Theory**:
- The Cosmozoic theory posits that life exists in the form of resistant spores that can survive space travel and that life was brought to Earth from outer space.
- **Conclusion**: This theory does not explain the origin of life from abiotic components on Earth, thus it is not consistent with abiogenesis.

5. **Analyzing Option (d): Theory of Panspermia**:
- Panspermia suggests that life exists throughout the universe and can be distributed by space dust or meteoroids. It implies that life did not originate on Earth but was brought here from elsewhere.
- **Conclusion**: This theory does not support the concept of abiogenesis, which focuses on the origin of life from non-living matter on Earth.

### Final Answer:
Based on the analysis, the correct answer is:
**(a) Theory of Spontaneous Creation**
