• B. It is completely resistant to all insect pests and diseases
• C. It gives high yields but not characteristic aroma
• D. It gives high yields and rich in vitamin A

Answer 1

The correct option is D It gives high yields and rich in vitamin A

Rice is a staple food in many countries, particularly in Asia, but does not contain vitamin A or its immediate precursors. By inserting two genes from Daffodil and one gene from a bacterial species into rice plants, Swiss researchers have produce rice capable of synthesizing β-carotene, the precursor of vitamin A. Vitamin A is required by all individuals as it is present in retina of eyes. Deficiency of vitamin A causes night blindness and skin disorders. This rice is called 'Golden rice' because of the yellow colour of rice grains due to the presence of β-carotene.

So, the correct answer is 'It gives high yields and rich in vitamin A'.
