The correct option is B 1992
The Policy Statement for Abatement of Pollution, adopted in 1992 lays emphasis on pollution prevention in place of the conventional end-of-the-pipe treatment also identified the adoption of best available and practicable technologies as the key element for pollution prevention. The focus of the programme is on such issues such as the promotion of clean and low waste technologies, waste minimization, reuse or recycling, improvement of water quality, environment audit, natural resource accounting, development of mass-based standards, institutional and human resource development etc. The whole issue of pollution prevention and control is dealt with by a combination of command and control methods as well as voluntary regulations, fiscal measures, promotion of awareness etc.
