B. (iii) and (iv)
C. (ii) and (iv)
D. (i) and (ii)

Answer

To determine which of the terms listed are not technically correct names for a floral whorl, we need to analyze each term in relation to the correct botanical terminology for the parts of a flower.

### Step-by-Step Solution:

1. **Understanding Floral Whorls**:
- A floral whorl refers to the arrangement of floral parts in a flower. There are four main whorls in a flower: calyx, corolla, androsium, and gynosium.

2. **Identifying Each Term**:
- **(i) Androsium**: This term refers to the male reproductive part of the flower, which consists of stamens (anther and filament). This is a correct term.
- **(ii) Carpel**: A carpel is a part of the female reproductive structure of a flower, but the technical term for the entire whorl of carpels is "gynosium." Therefore, "carpel" is not the correct technical term for the whorl.
- **(iii) Corolla**: This term refers to the whorl of petals in a flower. It is indeed the correct technical term for this part of the flower.
- **(iv) Sepal**: The term "sepal" refers to the individual parts of the outermost whorl, but the correct technical term for the entire whorl of sepals is "calyx." Thus, "sepal" is also not the correct technical term for the whorl.

3. **Conclusion**:
- The terms that are not technically correct names for a floral whorl are **(ii) Carpel** and **(iv) Sepal**.

### Final Answer:
The terms that are not technically correct names for a floral whorl are **Carpel** and **Sepal**.
