In the context of which one of the following are the terms 'pyrolysis and plasma gasification' mentioned?
A
Extraction of rare earth elements
B
Natural gas extraction technologies
C
Hydrogen fuel-based automobiles
D
Waste-to-energy technologies
Correct answer
Explanation
Pyrolysis and plasma gasification are advanced thermal processes used in waste-to-energy technologies to convert municipal solid waste into syngas, heat, or electricity in oxygen-limited environments. While "gasification" might tempt one toward natural gas extraction (Option B), these terms specifically refer to the chemical decomposition of waste materials rather than the geological recovery of fossil fuels. The core concept tested is sustainable solid waste management and the technological methods used to minimize landfill use while generating energy.
