Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

To solve the question regarding the definitions of biopoiesis and biogenesis, we can break it down into the following steps:

### Step 1: Understand the Assertion
The assertion states that "the branch of biology which deals with the study of the origin of life is called biopoiesis."

- **Explanation**: Biopoiesis refers to the study of how life originated from non-living matter. It is a theoretical framework that explores the processes that could have led to the emergence of life on Earth.

### Step 2: Understand the Reason
The reason provided is that "biogenesis is the process of origin of life from pre-existing life."

- **Explanation**: Biogenesis is a biological principle that states that living organisms arise from pre-existing life. This concept is often contrasted with abiogenesis, which is the idea that life can arise from non-living matter.

### Step 3: Analyze the Relationship Between Assertion and Reason
Now, we need to determine if the reason correctly explains the assertion.

- **Explanation**: While both statements are correct, they refer to different concepts. The assertion focuses on the origin of life from non-living matter (biopoiesis), while the reason discusses the origin of life from existing living organisms (biogenesis). Therefore, the reason does not serve as a correct explanation for the assertion.

### Step 4: Conclusion
Based on the analysis, we conclude that both the assertion and reason are correct, but the reason does not correctly explain the assertion.

- **Final Statement**: The correct answer is that both the assertion and reason are correct, but the reason is not the correct explanation for the assertion.
