B. carpel
C. corolla
D. sepal

Explanation

To determine which terms among the options provided are not technically correct names for a floral whorl, we will analyze each term step by step.

### Step-by-Step Solution:

1. **Understanding Floral Whorls**:
- Floral whorls are the arrangements of floral organs in a flower. The main whorls include the androecium, gynoecium, corolla, and calyx.

2. **Analyzing Each Option**:
- **(i) Androecium**:
- This term refers to the male reproductive whorl of a flower, which consists of stamens. Since it represents a group of stamens, it is a technically correct term for a floral whorl.

- **(ii) Carpel**:
- A carpel is a single unit of the female reproductive structure in a flower. However, the collective term for multiple carpels is "gynoecium." Therefore, "carpel" is not a technically correct name for the entire whorl, making it an incorrect option.

- **(iii) Corolla**:
- The corolla refers to the whorl of petals in a flower. It is a collective term for petals and is technically correct.

- **(iv) Sepal**:
- A sepal is a single unit of the outermost whorl of a flower, which collectively is called the "calyx." Similar to the carpel, "sepal" is not a technically correct name for the entire whorl, making it another incorrect option.

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**.
