Answer : c
Hints & Solutions
(c) Golden rice (Oryza sativa) is a genetically modified crop. It biosynthesizes $\beta$-carotene which is the precursor of vitamin-A. Golden Rice was engineered from normal rice by Ingo Potrykus and Peter Beyer in the 1990s to help improve human health. Golden Rice has an engineered multi-gene biochemical pathway in its genome. This pathway produces betacarotene, a molecule that becomes vitamin A when metabolized by humans.
