The correct answer is: C. 1972

The Act established the Central Pollution Control Board and the State Pollution Control Boards to regulate water pollution. It also made it a punishable offense to pollute water resources.

  • Option A is the year when India gained independence from British rule.
  • Option B is the year when the Indian Constitution was adopted.
  • Option D is the year when the Environment (Protection) Act was enacted.
