Options

A. a-iv, b-iii, c-`ii`
B. b-ii, b-`i`, c-iii
C. c-`i`, b-ii, c-iii
D. a-iii, b-ii, c-`i`

Answer

To solve the matching question regarding types of placentation and their corresponding examples, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Placentation**:
- **Marginal Placentation**: This occurs when the ovules are attached along the margin of a single carpel.
- **Axile Placentation**: This occurs when the ovary is divided into two or more locules, and the ovules are attached to a central column.
- **Parietal Placentation**: This occurs when the ovules are attached to the inner wall of a unilocular ovary.
- **Basal Placentation**: This occurs when a single ovule is attached at the base of the ovary.

2. **Match Each Type with its Example**:
- **(a) Marginal Placentation**: The example given is **Pea**.
- **(b) Axile Placentation**: The example given is **Lemon**.
- **(c) Parietal Placentation**: The example given is **Mustard**.
- **(d) Basal Placentation**: The example given is **Sunflower**.

3. **Final Matching**:
- (a) Marginal Placentation → (iv) Pea
- (b) Axile Placentation → (iii) Lemon
- (c) Parietal Placentation → (ii) Mustard
- (d) Basal Placentation → (i) Sunflower

4. **Select the Correct Option**: Based on the matches, we can conclude that the correct option is:
- A → iv
- B → iii
- C → ii
- D → i

### Final Answer:
The correct matches are:
- (a) Marginal Placentation → (iv) Pea
- (b) Axile Placentation → (iii) Lemon
- (c) Parietal Placentation → (ii) Mustard
- (d) Basal Placentation → (i) Sunflower
