Answer

To solve the question, we need to fill in the blanks in the provided statements based on our knowledge of plant anatomy. Let's go through each statement step by step.

### Step-by-Step Solution

1. **Statement (i)**: In monocot root, a large number of vascular bundles are arranged in the form of a ______ around the central ______.
- **Answer**: The vascular bundles in a monocot root are arranged in the form of a **ring** around the central **pith**.
- **Filled Statement**: In monocot root, a large number of vascular bundles are arranged in the form of a **ring** around the central **pith**.

2. **Statement (ii)**: Due to the presence of ______, the endodermal cells do not allow wall-to-wall movement of substances between cortex and pericycle, in primary dicot root.
- **Answer**: The endodermal cells have **Casparian strips** which prevent wall-to-wall movement of substances.
- **Filled Statement**: Due to the presence of **Casparian strips**, the endodermal cells do not allow wall-to-wall movement of substances between cortex and pericycle, in primary dicot root.

3. **Statement (iii)**: The epidermis of stem of sunflower bears several unbranched _____ hair.
- **Answer**: The epidermis of the stem of sunflower bears several unbranched **multicellular** hair.
- **Filled Statement**: The epidermis of stem of sunflower bears several unbranched **multicellular** hair.

4. **Statement (iv)**: The central portion of a dicot stem is usually occupied by _____ comprising of thin-walled parenchymatous cells.
- **Answer**: The central portion of a dicot stem is usually occupied by **pith** comprising of thin-walled parenchymatous cells.
- **Filled Statement**: The central portion of a dicot stem is usually occupied by **pith** comprising of thin-walled parenchymatous cells.

### Summary of Answers
- (i) ring, pith
- (ii) Casparian strips
- (iii) multicellular
- (iv) pith

### Final Selection
Based on the filled statements, we can now look for the option that correctly fills the blanks in at least two of the statements.

- **Option A**: ring, pith (correct), hypodermis (incorrect)
- **Option B**: Casparian strips (correct), unicellular (incorrect)
- **Option C**: ring (correct), convex (incorrect)
- **Option D**: multicellular (correct), pith (correct)

The correct option that fits the blanks in at least two statements is **Option D**.
