Answer

To solve the question of matching the structures in List-I with the functions in List-II, we can follow these steps:

### Step 1: Understand the Structures and Their Functions
- **Nucleolus (A)**: This is a structure found within the nucleus of a cell. Its primary function is the synthesis of RNA, which is essential for ribosome formation.
- **Spherosomes (B)**: These are small, single-membrane-bound organelles involved in lipid storage and synthesis.
- **Glyoxysome (C)**: This organelle is involved in the beta-oxidation of fatty acids and the glyoxylate pathway, which is crucial for the metabolism of fats.
- **Plasmodesmata (D)**: These are channels that connect the cytoplasm of adjacent plant cells, facilitating the transport of macromolecules between them.

### Step 2: Match Each Structure with Its Function
- **A (Nucleolus)** matches with **4 (RNA synthesis)** because the nucleolus is responsible for synthesizing RNA.
- **B (Spherosomes)** matches with **1 (Lipid storage)** since spherosomes are involved in lipid storage and synthesis.
- **C (Glyoxysome)** matches with **2 (beta-oxidation of fatty acids)** as glyoxysomes contain enzymes for this process.
- **D (Plasmodesmata)** matches with **3 (Transport of macromolecules)** because they allow for the transport of materials between plant cells.

### Step 3: Write Down the Final Matches
- A → 4 (Nucleolus → RNA synthesis)
- B → 1 (Spherosomes → Lipid storage)
- C → 2 (Glyoxysome → beta-oxidation of fatty acids)
- D → 3 (Plasmodesmata → Transport of macromolecules)

### Step 4: Choose the Correct Option
Based on the matches:
- A4, B1, C2, D3 corresponds to option C.

### Final Answer
The correct match is:
- **A → 4**
- **B → 1**
- **C → 2**
- **D → 3**

Thus, the answer is **Option C**.
