alleryProtina, Shakti and Rathna are biofortified maize hybrids developed in India that are rich in:
AEdible oil content
BIron and zinc
CThe amino acid lysine
DBeta carotene
Answer & Solution
Correct answer: C. The amino acid lysine
1. The biofortification examples list Protina, Shakti and Rathna together as one set.
2. They are described as lysine-rich maize hybrids.
3. Beta carotene is associated with Golden Rice, not these maize hybrids, so option D is a trap.
4. Hence the answer is C.
