A: The process of synthesis of complex organic molecules from simpler ones, by the living organisms is called Anabolism.
R: Anabolism is always useful for the organisms.

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

### Step-by-Step Solution:

**Step 1: Understand the Assertion (A)**
The assertion states that "the process of synthesis of complex organic molecules from simpler ones, by living organisms is called Anabolism."
- **Explanation**: Anabolism is a metabolic pathway that constructs molecules from smaller units. It is essential for growth and repair in living organisms.

**Step 2: Understand the Reason (R)**
The reason states that "Anabolism is always useful for the organisms."
- **Explanation**: While anabolism is crucial for growth and development, it is not the only factor that determines its usefulness. The balance between anabolism and catabolism (the breakdown of complex molecules) is essential for overall health and growth.

**Step 3: Analyze the Relationship between A and R**
- Both statements are true, but the reason provided does not fully explain the assertion. Anabolism contributes to growth, but it must be balanced with catabolism for the organism to thrive.

**Step 4: Conclusion**
- Since both statements are true but the reason does not correctly justify the assertion, the correct answer is that both statements are true, but the reason is not the correct reason for the assertion.

### Final Answer:
Both statements are true, but the reason is not the correct reason for the assertion.
