Step 1: Understanding the Concept:
The question asks about the subject matter of the case Krishna Gopal v. State of M.P.. This case is a notable judgment in the field of environmental law.
Step 2: Detailed Explanation:
The case of Krishna Gopal v. State of M.P. (1995) is a landmark decision by the Madhya Pradesh High Court specifically addressing the issue of noise pollution.
The court was dealing with a petition against noise pollution caused by a factory in a residential area. In its judgment, the court recognized that the Right to Life under Article 21 of the Constitution includes the right to a clean and healthy environment, which in turn encompasses the right to live in a noise-free environment. It treated noise as a form of environmental pollution that adversely affects human health.
The options provided in the OCR seem to be mixed (e.g., noise and air pollution). While a factory might cause multiple types of pollution, the key legal principle established and discussed in this specific case was related to noise. Therefore, any answer not centered on noise pollution is less accurate. The primary focus of the case was noise.
Step 3: Final Answer:
The case of Krishna Gopal v. State of M.P. is fundamentally related to noise pollution.
