Statement (A) is correct because rice is highly consumed in Asia and accounts for approximately 40% of the daily protein in an average Asian diet.
Statement (B) is correct as rice supplies around 25% of the total protein requirement in India.
Statement (C) is correct because the overall protein concentration in polished rice is low, varying between 6% and 8%.
Statement (D) is correct because rice protein (oryzenin) has a higher biological value and contains more lysine compared to other major cereal grains.
Therefore, all four statements are true.
