(B) The slurry left over in a gobar gas plant is used as a clean cooking fuel. — Incorrect. The gas from the plant is the fuel. The slurry left over is a very good organic fertiliser and soil conditioner.
(C) Subsidised CNG is being provided to rural households in place of dung cake. — Incorrect. Rural households are given subsidised LPG, not CNG.

NCERT (2026-27): “7.5 Strategies for Sustainable Development … LPG, Gobar Gas in Rural Areas: Households in rural areas generally use wood, dung cake or other biomass as fuel. This practice has several adverse implications like deforestation, reduction in green cover, wastage of cattle dung and air pollution. To rectify the situation, subsidised LPG is being provided. In addition, gobar gas plants are being provided through easy loans and subsidy. As far as liquefied petroleum gas (LPG) is concerned, it is a clean fuel — it reduces household pollution to a large extent. Also, energy wastage is minimised. For the gobar gas plant to function, cattle dung is fed to the plant and gas is produced which is used as fuel while the slurry which is left over is a very good organic fertiliser and soil conditioner.” “CNG in Urban Areas: In Delhi, the use of Compressed Natural Gas (CNG) as fuel in public transport system has significantly lowered air pollution and the air has become cleaner. …” |
