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:

1. **Understanding the Assertion:**
- The assertion states that "a flower is a modified shoot which helps in sexual reproduction."
- Flowers are indeed the reproductive structures of angiosperms (flowering plants) and are responsible for sexual reproduction. They contain both male (stamens) and female (pistils) reproductive organs.

2. **Analyzing the Structure of a Flower:**
- The male part of the flower is called the stamen, which consists of the anther (where pollen is produced) and the filament.
- The female part is called the pistil (or gynoecium), which includes the ovary (where ovules are produced), style, and stigma.

3. **Understanding the Reason:**
- The reason states that "monoparental reproduction is also called vegetative reproduction."
- Monoparental reproduction refers to a type of reproduction involving only one parent, which is characteristic of asexual reproduction.

4. **Linking the Concepts:**
- Vegetative reproduction is a form of asexual reproduction where new plants grow from parts of the parent plant, such as roots, stems, or leaves.
- Therefore, the statement that monoparental reproduction is also called vegetative reproduction is correct.

5. **Evaluating the Relationship Between Assertion and Reason:**
- While both the assertion and reason are correct, the reason does not explain the assertion. The assertion pertains to sexual reproduction (involving flowers), while the reason discusses a form of asexual reproduction (vegetative reproduction).

6. **Conclusion:**
- Both the assertion and reason are correct, but the reason is not the correct explanation of the assertion. Therefore, the correct answer is that both statements are true, but the reason does not support the assertion.

### Final Answer:
Both the assertion and reason are correct, but the reason is not the correct explanation of the assertion.
