|A|| The grains have been fortied with genes to provide three times higher grain yield per acre than other high yielding varieties|
|B|| Its grains contain pro-vitamin A which upon ingestion is converted to vitamin A in the human body|
|C|| Its modified genes cause the synthesis of all the nine essential amino acids|
|D|| Its modified genes cause the fortification of its grains with vitamin D|
Ans. B Exp: Golden rice is a variety of Oryza sativa rice produced through genetic engineering to biosynthesize beta-carotene, a precursor of pro-vitamin A in the edible parts of rice. The scientific details of the rice were first published in Science in 2000. Golden rice was developed as a fortified food to be used in areas where there is a shortage of dietary vitamin A. In 2005 a new variety called Golden Rice 2 was announced which produced up to 23 times more beta-carotene than the original variety of golden rice. Neither variety is currently available for human consumption. Although golden rice was developed as a humanitarian tool, it has met with significant opposition from environmental and antiglobalization activists.
