A) Give high yield but has no characteristic aroma
B) Does not require chemical fertilizers and growth hormones
C) Gives high yield and is rich in vitamin A
D) Is completely resistant to all insect pests and diseases of paddy
Explanation
[Solution from source] Transgenic rice has been engineered with genes for β-carotene (the vitamin A precursor), known as Golden Rice, so 'rich in vitamin A' is the intended answer. No crop is completely resistant to all pests, none can do without fertilisers, and losing the aroma would not count as an improvement. Answer (3).
