Updated On: Jun 6, 2026
- Zn
- Fe
- Mo
- Mn
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Mineral nutrition and enzyme activation in plants.
Step 2: Meaning
IAA oxidase is an enzyme involved in the degradation of Indole-3-Acetic Acid (IAA), an auxin.
Step 3: Analysis
Manganese (Mn) is known to act as an activator for various enzymes, specifically including IAA oxidase, which regulates auxin levels in plants.
Step 4: Conclusion
Mn is the correct activator for IAA oxidase.
