Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Functions of plant growth regulators.
Step 2: Meaning
Cytokinins promote cell division and play specific roles in leaf and bud development.
Step 3: Analysis
Cytokinins are responsible for chloroplast production in leaves and help overcome apical dominance by promoting lateral bud growth.
Step 4: Conclusion
Functions I and IV are associated with cytokinin.
Final Answer: (C)
