Go through the following mathces
(i) Cotton - Open aestivation
(ii) Lady finger - Quincuncial aestivation
(iii) Cassia - Ascending imbricate aestivation
(iv) Bean - Descending imbricate aestivation
Which of these are correct ?

Options

A. (i), (iii) & (iv)
B. (iii) and (iv)
C. (ii), (iii) and (iv)
D. All are correct.

Answer

To determine which of the given matches regarding plants and their types of aestivation are correct, we will analyze each match step by step.

### Step 1: Analyze the first match - Cotton and Open Aestivation
- Cotton is known to have closed aestivation, not open.
- **Conclusion**: This match is incorrect.

### Step 2: Analyze the second match - Lady Finger and Quincuncial Aestivation
- Lady Finger (Okra) does not exhibit quincuncial aestivation. Instead, it typically has a different type of aestivation.
- **Conclusion**: This match is also incorrect.

### Step 3: Analyze the third match - Cassia and Ascending Imbricate Aestivation
- Cassia is known to have ascending imbricate aestivation, where the petals overlap each other in a specific manner.
- **Conclusion**: This match is correct.

### Step 4: Analyze the fourth match - Bean and Descending Imbricate Aestivation
- Beans exhibit descending imbricate aestivation, where the older petals are on the inside and overlap the younger petals.
- **Conclusion**: This match is also correct.

### Final Conclusion:
- The correct matches are:
- (iii) Cassia - Ascending imbricate aestivation (Correct)
- (iv) Bean - Descending imbricate aestivation (Correct)
- Therefore, the correct options are matches (iii) and (iv).
