NISHANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant hormone bioassays
	**Related Topics**: Auxins, Avena coleoptile, Plant physiology
	**Prerequisites**: Knowledge of plant hormones and their functions
## SOLUTION PATHWAY
**Given Information**:
	The question asks about the hormone used in the Avena curvature test.
**Method & Steps**:
	1.	Recall the Avena curvature test and the hormone it is used to assay
		Reasoning: The Avena curvature test is a classic bioassay for auxins.
		Formula/Rule: None
	2.	Identify the correct auxin among the options.
		Working: ${m{IAA}}$ (Indole-3-acetic acid) is the most common naturally occurring auxin.
		Key Point: The Avena coleoptile is very sensitive to auxins
	3.	Select the correct option
		Result: ${m{IAA}}$ is the correct answer.
		Verification: The Avena curvature test is a standard bioassay for auxins.
 ## OPTION ANALYSIS
[A] :x: ABA (Abscisic acid) is not primarily assayed using the Avena curvature test.
[B] :x: GA3 (Gibberellic acid) is a different class of hormone and not the target of this assay.
[C] ✓: IAA (Indole-3-acetic acid) is the correct answer; it's the primary hormone tested in the Avena curvature bioassay.
[D] :x: Ethylene is a gaseous plant hormone and is not assayed with this test
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing different plant hormones and their bioassays.
			[How to avoid]: Learn the specific bioassays used for each major plant hormone.
	**Quick Tips**:
		1.[Helpful shortcut]: Remember that Avena curvature is specifically linked to auxins, particularly IAA.
