Answer

To solve the question regarding the type of flower where sepals or petals in a whorl touch each other at the margins without overlapping, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Estivation**:
- Estivation refers to the arrangement of sepals or petals in a flower bud before it opens. It is crucial to know the different types of estivation to answer the question correctly.

2. **Identify the Types of Estivation**:
- There are several types of estivation, including:
- **Valvate**: Margins touch but do not overlap.
- **Imbricate**: Margins overlap.
- **Twisted**: One margin overlaps the next in a spiral.
- **Vexillary**: A specific arrangement seen in pea flowers where one petal is larger and overlaps the others.

3. **Analyze the Options Given**:
- The options provided are:
- A) Cassia - which has imbricate estivation (overlapping).
- B) Ladies Finger - which has twisted estivation (overlapping).
- C) Pea - which has vexillary estivation (overlapping).
- D) Callotropis - which has valvate estivation (margins touch without overlapping).

4. **Determine the Correct Answer**:
- Since the question specifies that the sepals or petals touch at the margins without overlapping, the correct type of estivation is **valvate**. Among the options, **Callotropis** is the only flower that exhibits this type of estivation.

5. **Conclude**:
- Therefore, the correct answer to the question is **D) Callotropis**.
