(iii) Corolla (iv) Sepal,

Options

C. ii and iv
D. i and ii

Answer

To solve the question regarding which terms are not technically correct names for a floral whorl, let's analyze each term step by step.

### Step 1: Understand the Floral Structure
A complete flower consists of four main floral whorls arranged from the outermost to the innermost:
1. **Calyx** - made up of sepals
2. **Corolla** - made up of petals
3. **Androecium** - made up of stamens (the male reproductive part)
4. **Gynoecium** - made up of carpels (the female reproductive part)

### Step 2: Analyze Each Term
- **(i) Androecium**: This is the correct term for the male whorl of the flower, which consists of stamens. Therefore, it is a technically correct name for a floral whorl.

- **(ii) Carpel**: This refers to a single unit of the gynoecium (the female part of the flower). While it is part of the floral structure, it is not a term that represents a complete floral whorl. Hence, it is not a technically correct name for a floral whorl.

- **(iii) Corolla**: This is the correct term for the whorl of petals in a flower. Thus, it is a technically correct name for a floral whorl.

- **(iv) Sepal**: This refers to an individual part of the calyx, which is the outermost whorl of the flower. Like the carpel, it is not a term that represents a complete floral whorl. Therefore, it is also not a technically correct name for a floral whorl.

### Step 3: Identify Incorrect Terms
From the analysis:
- The terms that are not technically correct names for a floral whorl are **Carpel (ii)** and **Sepal (iv)**.

### Conclusion
The answer to the question is that the terms that are not technically correct names for a floral whorl are:
- **Carpel (ii)**
- **Sepal (iv)**

Thus, the correct answer is option **C** (Carpel and Sepal).
