Assertion: The process including separation & purification of product are collectively referred as downstream processing
Reason :The downstream processing & quality control testing are same for all type of products

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion
B. It both Assertion & Reason are True but Reason is not a correct explanation of the Assetion
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are false

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that the process including separation and purification of products is collectively referred to as downstream processing. This is true. Downstream processing involves the steps taken after fermentation or production to isolate and purify the desired product from the bulk mixture.

2. **Understanding the Reason**: The reason given is that downstream processing and quality control testing are the same for all types of products. This is false. Different products require different downstream processing techniques and quality control measures based on their unique properties and requirements.

3. **Evaluating the Truth of Assertion and Reason**:
- The assertion is true because downstream processing does indeed refer to the separation and purification processes.
- The reason is false because the methods of downstream processing and quality control testing vary significantly depending on the type of product being processed.

4. **Conclusion**: Since the assertion is true and the reason is false, the correct answer is that the assertion is true, but the reason is false.

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