Answer: 1. It is Vitamin A enriched, with a gene from daffodil.

Key idea: Golden rice is a biofortified rice rich in provitamin A (beta-carotene).

It was made by introducing genes for the carotene pathway, with the gene taken from daffodil (Narcissus), so it is vitamin A enriched. Bt genes give pest resistance in cotton, not golden rice; golden rice is not about drought tolerance; its yellow colour is due to beta-carotene, not a gene from a primitive rice variety.
