Correct option is C
The correct answer is (c).
Evaluating the statements strictly on chemical and physical realities: Fossil fuels absolutely cannot be synthesized artificially in labs;
CNG is vastly cleaner than petrol; Coke is highly pure carbon; Coal tar is completely recognized as a complex mixture of hundreds of distinct hydrocarbon compounds.
Information Booster
- Statement A (False): True fossil fuels strictly require millions of years of intense subterranean geological pressure and extreme heat acting on massive organic deposits; they cannot be instantly replicated in standard laboratories.
- Statement B (False): Compressed Natural Gas (CNG), primarily methane, burns immensely cleaner, completely emitting zero particulate matter and far fewer toxic nitrogen oxides compared to dense liquid petrol.
- Statement C (True): Coke is a tough, extremely porous, high-carbon residue artificially produced by violently heating massive amounts of bituminous coal in the total absence of air (destructive distillation), rendering it almost completely pure carbon.
- Statement D (True): Coal tar is an intensely thick, incredibly complex, extremely foul-smelling liquid strictly comprising hundreds of varying aromatic hydrocarbons widely utilized for massive synthetic dye production.
- Coal processing yields vital industrial cornerstones; the intense destructive distillation of raw coal creates Coke, Coal Tar, and Coal Gas sequentially.
- Coke is universally demanded as an irreplaceable, absolute reducing agent for massive industrial iron-smelting blast furnaces worldwide.
- Understanding true fuel refinement processes is absolutely critical to deeply analyze total global carbon footprints and lifecycle emissions.
- Why the other logical sets fail: If statement A and B are blatantly false, any option claiming "All true" is immediately eliminated.
- The extreme toxicity of raw coal tar strictly classifies it as a hazardous waste requiring massive specialized handling during industrial coking operations.
- Biofuels (like massive synthetic ethanol) can be synthesized in advanced bioreactors, but true crude oil is fundamentally constrained by millions of years of agonizingly slow geological diagenesis.
- Environmental science fundamentally differentiates strictly between pristine natural resources and complex, highly refined industrial hydrocarbon byproducts.
