Question

Match items in List I with items in List II:

• A. A-III, B-I, C-IV, D-II
• B. A-IV, B-III, C-II, D-I
• C. A-III, B-IV, C-I, D-II
• D. A-II, B-I, C-IV, D-III

Hint:

Meristem = Virus-free. bar = Herbicide. gai = Gibberellin (Growth) mutant.

Answer 1

The Correct Option is D

Step 1: Concept
Identify the role of specific genes and tissue culture techniques.

Step 2: Meaning
The *bar* gene confers resistance to the herbicide glufosinate.

Step 3: Analysis
A-II (Herbicide). Meristem culture is famously used to produce virus-free plants (B-I). Chalcone Synthase is a key enzyme in the flavonoid pathway responsible for flower color (C-IV). The *gai* gene is involved in gibberellin signaling, leading to dwarfism (D-III).

Step 4: Conclusion
The correct matching is A-II, B-I, C-IV, D-III. Final Answer: (D)
