Which is a genetically modified crop?
Correct answer: D. All
- A. Bt-cotton
- B. Bt-brinjal
- C. Golden rice
- D. All
Explanation
Bt cotton, Bt brinjal and Golden Rice are all genetically modified crops because each contains introduced genetic material that gives a desired trait. A student may hesitate over Golden Rice because its modification improves nutrition rather than insect resistance, but nutritional improvement is also a genetically engineered trait.
