Go through the following matches
`{:((i),"Primary diocot stem",-"Sclerenchymatous hypodermis"),((ii),"Monocot stem",-"Parenchymatous pit"),((iii),"Dicot leaf",-"Praenchymatous pith"),((iv),"Monocot leaf",-"Bulliform cells"):}`
Which or the following

Answer

To analyze the matches provided in the question, we will go through each item step by step and determine their correctness based on the anatomical characteristics of flowering plants.

### Step-by-Step Solution:

1. **Match (i): Primary Dicot Stem - Sclerenchymatous Hypodermis**
- In a primary dicot stem, the hypodermis is typically composed of collenchyma, not sclerenchyma. Sclerenchyma is usually found in older stems or in other plant parts for support.
- **Conclusion:** This match is incorrect.

2. **Match (ii): Monocot Stem - Parenchymatous Pit**
- In monocot stems, the term "pit" is not typically used as they do not have a pith. Instead, they have a vascular bundle arrangement that is scattered throughout the stem.
- **Conclusion:** This match is also incorrect.

3. **Match (iii): Dicot Leaf - Parenchymatous Pith**
- In dicot leaves, the pith is absent. The leaf structure primarily consists of mesophyll, which is made up of parenchyma, but there is no pith as seen in stems.
- **Conclusion:** This match is incorrect.

4. **Match (iv): Monocot Leaf - Bulliform Cells**
- Monocot leaves do contain bulliform cells, which are specialized cells that help in the regulation of water loss by folding or rolling the leaf during dry conditions. These cells are indeed hygroscopic and play a crucial role in water conservation.
- **Conclusion:** This match is correct.

### Final Analysis:
- The only correct match is (iv): Monocot Leaf - Bulliform Cells.
- All other matches (i, ii, iii) are incorrect.
