Question

Identify wrong matching I. \= Roundup ready = Soyabean \hspace{1cm} = Herbicide tolerant
II. \= Transgenic Plant = Papaya \hspace{1cm} = Pseudomonas resistant
III. \= Taipei variety = Rice \hspace{1cm} = rich in Vitamin B
IV. \= Flavr savr = Tomato \hspace{1cm} = Bruise resistant

• A. \( \text{I and IV} \)
• B. \( \text{III and IV} \)
• C. \( \text{II and III} \)
• D. \( \text{I and II} \)

Hint:

Remember, transgenic plants are often modified for specific traits, such as disease resistance, improved nutritional content, or physical traits like bruise resistance.

Answer 1

The Correct Option is C

Understanding the correctness of each match
- I - Roundup ready = Soyabean = Herbicide tolerant (Correct)
- Roundup Ready soybeans are genetically modified to be resistant to glyphosate-based herbicides.
- II - Transgenic Plant = Papaya = Pseudomonas resistant (Incorrect)
- Transgenic Papaya is genetically modified to resist Papaya Ringspot Virus (PRSV), not Pseudomonas.
- Therefore, this match is incorrect.
- III - Taipei variety = Rice = Rich in Vitamin B (Incorrect)
- Taipei variety of rice is not specifically known for being rich in Vitamin B.
- The most well-known Vitamin B-enriched rice is Golden Rice, which is biofortified with Vitamin A, not Vitamin B.
- Therefore, this match is incorrect.
- IV - Flavr Savr = Tomato = Bruise resistant (Correct)
- The Flavr Savr tomato is genetically engineered to delay softening and bruising.
Step 2: Examining the given options
- Option 1 (I and IV) → Incorrect (Both are correct).
- Option 2 (III and IV) → Incorrect (III is incorrect, but IV is correct).
- Option 3 (II and III) → Correct, as both II and III contain incorrect matches.
- Option 4 (I and II) → Incorrect (I is correct).
Step 3: Conclusion Since Papaya is resistant to PRSV, not Pseudomonas, and Taipei rice is not known for Vitamin B enrichment, the correct answer is Option (3): II and III.
