  1. (a) 1, 2, 5 and 6 only ✓ UPSC's answer
  2. (b) 1, 3, 4 and 6 only
  3. (c) 2, 3, 4 and 5 only
  4. (d) 1, 2, 3, 4, 5 and 6

Why the answer is (a)

• The National Policy on Biofuels, 2018 widens ethanol feedstocks to sugarcane juice, sugar-containing materials like sugar beet and sweet sorghum, starch-containing materials like corn and cassava, and damaged food grains (wheat, broken rice) and rotten potatoes unfit for human consumption.

• Cassava (1), damaged wheat (2), rotten potatoes (5) and sugar beet (6) are therefore permitted.

• Groundnut seeds (3) and horse gram (4) are edible oilseed/pulse crops, not listed as biofuel feedstock.

• Hence 1, 2, 5 and 6 only, option (a).

Why the other options are wrong

(b) 1, 3, 4 and 6 only
Groundnut and horse gram are not listed feedstocks.
(c) 2, 3, 4 and 5 only
Groundnut and horse gram are not listed; sugar beet is.
(d) 1, 2, 3, 4, 5 and 6
Groundnut and horse gram are excluded.
