Question

An improved variety of transgenic basmati rice

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [B]
## CONCEPT FRAMEWORK
	**Primary Concept**: Transgenic crop improvements
	**Related Topics**: Agricultural biotechnology, Nutritional enhancement
	**Prerequisites**: Basic understanding of transgenic crops and their benefits
## SOLUTION PATHWAY
**Given Information**:
		- Improved variety of transgenic basmati rice
		- Options regarding its characteristics
**Method & Steps**:
	1. Identify the benefits of transgenic crops.
		Reasoning: Transgenic crops are often developed to enhance specific traits such as yield and nutritional value.
		Formula/Rule: N/A
	2. Evaluate each option based on known characteristics of improved transgenic varieties.
		Working: 
		- Option A: Chemical fertilizers and hormones may be reduced but not eliminated.
		- Option B: High yield and vitamin A enrichment is a common goal for transgenic crops.
		- Option C: Complete resistance to all pests is unrealistic; some may still affect.
		- Option D: Improvement often includes aroma retention; high yield does not mean loss of aroma.
	3. Conclude which option best represents the improved variety's characteristics.
		Result: Option B aligns with the known goals of transgenic rice varieties.
		Verification: High-yield, vitamin A-rich rice varieties exist and are beneficial.
 ## OPTION ANALYSIS
[A] :x: Does not require chemical fertilizers and growth hormones: While transgenic crops aim to reduce reliance on chemicals, complete elimination is unlikely.
[B] ✓: Gives high yield and is rich in vitamin-A: This is a primary objective of many improved transgenic rice varieties, making it a correct choice.
[C] :x: Is completely resistant to all insect pests and diseases of paddy: No crop can be entirely pest and disease-proof; some vulnerabilities remain.
[D] :x: Gives high yield but has no characteristic aroma: Many improved varieties seek to retain desirable traits like aroma while also increasing yield.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing increased yield with loss of traditional traits: Understand that improvements can maintain key characteristics.
		2. Overestimating the effectiveness of transgenic resistance: Recognize that no crop is entirely pest-resistant.
	**Quick Tips**:
		1. Remember the primary goals of transgenic crops: yield improvements and nutritional enhancements.
		2. Keep in mind the balance between modern techniques and traditional crop traits.
