B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion
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 "Ultrafiltration takes place in presence of effective filtration pressure."
- This is true because ultrafiltration occurs in the kidneys, specifically in the renal corpuscles, where blood is filtered under the influence of effective filtration pressure.

2. **Understanding the Reason**:
- The reason states that "In ultrafiltration process blood is filtered in Bowman's capsule, and the filtered fluid contains protein and blood corpuscles."
- While it is true that blood is filtered in Bowman's capsule, the statement about the filtered fluid is incorrect. The filtrate primarily contains water, glucose, salts, and urea, but it does not contain proteins or blood corpuscles, as these are too large to pass through the filtration barrier.

3. **Evaluating the Correctness of Assertion and Reason**:
- Since the assertion is true and the reason is false, we conclude that the assertion is correct while the reason is not.

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

### Final Answer
- The assertion is true, but the reason is false.
