According to India's National Policy on Biofuels, which of the following can be used as raw materials for the production of biofuels ? 1. Cassava 2. Damaged wheat grains 3. Groundnut seeds 4. Horse gram 5. Rotten potatoes 6. Sugar beet Select the correct answer using the code given below:

1. India's National Policy on Biofuels - 2018 expanded the scope of raw materials for ethanol production. 2. Statement 1 (Cassava): This is a starch-containing material explicitly allowed as a feedstock for ethanol production under the policy. (Correct) 3. Statement 2 (Damaged wheat grains): The policy allows the use of food grains unfit for human consumption, such as damaged wheat grains, for ethanol production. (Correct) 4. Statement 3 (Groundnut seeds): These are primarily edible oilseeds. While oils can be used for biodiesel, the policy emphasizes non-edible oilseeds. Groundnut seeds are not typically used for ethanol production and are a valuable food source. (Incorrect) 5. Statement 4 (Horse gram): This is a pulse crop used for food and feed. It is not listed as a feedstock for biofuel production under the policy. (Incorrect) 6. Statement 5 (Rotten potatoes): The policy allows starch-containing materials unfit for human consumption, like rotten potatoes, to be used for ethanol production. (Correct) 7. Statement 6 (Sugar beet): This is explicitly mentioned in the policy as a sugar-containing material suitable for ethanol production. (Correct) 8. Therefore, Cassava, Damaged wheat grains, Rotten potatoes, and Sugar beet (1, 2, 5, and 6) can be used as raw materials.
