Question

Rice variety with five times more ................ has been developed.

• A. tryptophan
• B. vitamin B12
• C. iron
• D. protein

Hint:

Iron-fortified rice is part of biofortification efforts to address nutrient deficiencies, especially in areas where rice is a staple food.

Answer 1

The Correct Option is C

Step 1: Understanding the development of rice variety.
A genetically modified rice variety has been developed that contains five times more iron, which addresses iron deficiency issues in populations that rely on rice as a staple food.
Step 2: Analyzing the options.
(A) tryptophan: Incorrect — Tryptophan is an amino acid, but it is not the focus of this particular rice variety development.
(B) vitamin B12: Incorrect — Vitamin B12 is important, but it is not the focus of this genetically modified rice.
(C) iron: Correct — The rice variety has been developed to contain five times more iron.
(D) protein: Incorrect — Protein content is important, but the focus in this case is on iron.
Step 3: Conclusion.
The correct answer is (C) iron, as the rice variety has been developed with five times more iron to combat iron deficiency.
