Identify the wrongly matched pair with reference to the post fertilisation changes in a flowering plant.

Options

A. Ovary-fruit
B. Ovule-seed
C. Ovary wall-seed coat
D. Sepals-shriveled

Explanation

To identify the wrongly matched pair with reference to the post-fertilization changes in a flowering plant, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Post-Fertilization Changes**: After fertilization in flowering plants, several changes occur. The ovary develops into a fruit, the ovule develops into a seed, and the ovary wall changes to form the fruit wall.

2. **Analyze Each Option**:
- **Option 1: Ovary → Fruit**: This is correct. The ovary develops into the fruit after fertilization.
- **Option 2: Ovule → Seed**: This is also correct. The ovule develops into a seed after fertilization.
- **Option 3: Ovary wall → Seed coat**: This is incorrect. The ovary wall does not develop into the seed coat; instead, it develops into the fruit wall.
- **Option 4: Sepals → Shrivel**: This is generally correct as sepals may wither away after fertilization.

3. **Identify the Wrongly Matched Pair**: From the analysis, the wrongly matched pair is "Ovary wall → Seed coat" because the ovary wall develops into the fruit wall, not the seed coat.

4. **Conclusion**: The answer to the question is the pair "Ovary wall → Seed coat".

### Final Answer:
The wrongly matched pair is **Ovary wall → Seed coat**.
