C. If Assertion is True but the Reason is Flase.
D. If both Assertion & Reason are false.

Answer

To analyze the assertion and reason provided in the question, we will break down the concepts of genetic information transmission and the role of RNA and DNA in protein synthesis.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "In the same generation for transmission of genetic information, RNA is better than DNA."
- To evaluate this, we need to consider the roles of RNA and DNA in genetic information transmission. DNA is typically the genetic material in most organisms, while RNA plays a crucial role in protein synthesis and can also serve as genetic material in some viruses.

2. **Understanding the Reason**:
- The reason given is that "The protein synthesizing machinery has evolved around RNA."
- This is true because ribosomes, which are the sites of protein synthesis, utilize mRNA (a type of RNA) as a template to synthesize proteins. The evolutionary perspective suggests that early life forms may have relied more on RNA for both genetic information and catalysis (as seen in ribozymes).

3. **Evaluating the Relationship**:
- The assertion claims that RNA is better than DNA for the transmission of genetic information in the same generation. This is a contentious statement because while RNA plays a vital role in protein synthesis, DNA is the stable genetic material that is inherited across generations in most organisms.
- The reason supports the assertion by highlighting the central role of RNA in the protein synthesis machinery, but it does not necessarily validate the assertion that RNA is "better" than DNA for genetic transmission.

4. **Conclusion**:
- The assertion is misleading because while RNA is crucial in the process of protein synthesis, DNA is the primary genetic material responsible for the transmission of genetic information across generations. Therefore, the assertion is false, while the reason is true.

### Final Answer:
- **Assertion**: False
- **Reason**: True
