Solution

The correct option is B Both assertion and reason are true but the reason is not the correct explanation for the assertion
Biofortification is a plant breeding programme that aims at the improved nutritional quality of crops with higher levels of vitamins, proteins, minerals etc.

Golden rice (Oryza sativa ) is a biofortified (containing enhanced nutritional content) variety of rice produced by introducing the gene for ꞵ - carotene synthesis from daffodil into the genome of normal rice enabling it to sysnthesis ꞵ - carotene, a precursor of vitamin A. So that it can help in eliminating the night blindness caused due to vitamin A deficiency. Night blindness is the inability to see well at night or in poor light conditions.

Due to the accumulation of ꞵ - carotene in the endosperm (the part of seed that stores food for the development of embryo) of seed, golden rice apperas golden yellow in colour.

Hence, both assertion and reason are true statements but the reason is not the correct explanation for the assertion.
