Step 1: Match each organelle with its function.
• Nucleolus → site of RNA synthesis (4).
• Sphaerosomes → store lipids in plant cells (1).
• Peroxisomes → involved in fatty acid breakdown via β-oxidation (2).
• Plasmodesmata → facilitate transport of macromolecules between plant cells (3).
Step 2: Match with provided options.
Only option (B) corresponds to the correct mapping:
P-4, Q-1, R-2, S-3.
Step 3: Conclusion.
Thus, option (B) correctly matches organelles with their functions.
