B. If both Assertion & Reason are True & the Reason is 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 "In mustard flowers, the flowers are hypogynous."
- Hypogynous flowers are characterized by having the ovary positioned above the other floral parts (such as petals and sepals).

2. **Understanding the Reason**: The reason provided is "In mustard flowers, other floral whorls are present above the level of the ovary."
- This implies that in mustard flowers, the petals and sepals are located above the ovary, which contradicts the definition of hypogynous flowers.

3. **Analyzing the Assertion**: The assertion is indeed true. Mustard flowers are classified as hypogynous because the ovary is superior, meaning it is positioned above the other floral parts.

4. **Analyzing the Reason**: The reason is false. In hypogynous flowers, the other floral whorls (petals, sepals, and stamens) are located below the ovary, not above it.

5. **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:
The correct option is: **Assertion is true but the reason is false.**
