According to India's National Policy o 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 :

Gives the policy's explicit examples of materials allowed for ethanol production (sugar beet, sweet sorghum, starch materials, damaged food grains, rotten potatoes), showing the policy's pattern of listing specific sugar/starch and waste feedstocks.

A student could use this pattern to ask whether the policy similarly lists oilseeds (like groundnut) for biodiesel or whether the policy confines examples to sugar/starch/waste feedstocks.

Notes that amendments (June 2023) made 'additional feedstocks' eligible to meet ethanol blending targets, indicating the policy can be expanded to include new raw materials.

A student could check post-amendment lists to see if oilseeds or groundnut were among the newly eligible feedstocks.

Explains that groundnut is a major oilseed and that some oilseeds are used as raw material for industrial purposes (soap, cosmetics), implying groundnut is an established source of oil that could, in principle, serve as biodiesel feedstock.

A student could combine this with knowledge that biodiesel is produced from vegetable oils to assess plausibility that groundnut oil might be considered for biodiesel under the policy.

Defines oilseed crops (including groundnut) as crops cultivated for oil for edible, industrial or medicinal purposes and notes high oil content in seeds, which is the relevant property for biodiesel feedstocks.

A student could use this to infer that if the policy allows vegetable oils or oilseeds for biodiesel, groundnut seeds would fit that technical criterion and should be looked for in the policy's biodiesel feedstock list.

This study/exam item explicitly lists 'Horse gram' among candidate raw materials in a question about which materials can be used under the National Policy on Biofuels, indicating the crop is considered in question banks as a possible option.

A student could check the official enumerated list in the policy (or updated lists) to see if horse gram appears, treating this item as hinting that horse gram has been discussed in this context.

This snippet gives the policy's explicit allowed feedstock list (e.g., B-molasses, sugar beet, sweet sorghum, cassava, damaged food grains, rotten potatoes) and does not include horse gram, showing the core 2018 list omits it.

A student can use this as a baseline (2018 policy contents) and then check whether later amendments added horse gram to the list.

Notes that in June 2023 the Central Government amended the National Policy on Biofuels to make additional feedstocks eligible for biofuel production.

A student should compare the 2018 list (snippet 3) with the 2023 amendment documents to see if horse gram was among the newly eligible feedstocks.

Defines bioenergy as derived from plant materials and notes biofuels from plant materials are a major renewable technology, framing that pulses/legumes could plausibly be candidate feedstocks in principle.

A student could use this general definition plus knowledge of horse gram as a plant/legume to assess plausibility and then verify policy lists for explicit inclusion.
