(B) Industrial activity is not a significant contributor to water pollution
(C) Air pollution cause various diseases related to respiratory nervous and circulatory system
(D) Noise pollution is location specific and its intensity declines with increase in distance from the sources of pollution
Choose the correct answer from the options given below :
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A), (C), (D) only
(A) Environmental pollution results from the release of substances and energy from waste products of human activities — True. This is the definition of environmental pollution.
(B) Industrial activity is not a significant contributor to water pollution — False. Among the human activities that pollute water, industry is the most significant contributor. NTA changed the words of the book, and a true line became false. Read every word before you mark the answer.
(C) Air pollution cause various diseases related to respiratory nervous and circulatory system — True. Polluted air harms the respiratory, nervous and circulatory systems.
(D) Noise pollution is location specific and its intensity declines with increase in distance from the sources of pollution — True. Noise is loudest near its source, such as industrial areas, transport routes and airports, and becomes weaker farther away.
NCERT (2026-27): “Environmental Pollution Environmental pollution results from ‘the release of substances and energy from waste products of human activities.” “Though water pollutants are also created from natural sources (erosion, landslides, decay and decomposition of plants and animals, etc.) pollutants from human activities are the real causes of concern. Human beings pollute the water through industrial, agricultural and cultural activities. Among these activities, industry is the most significant contributor.” “Air pollution causes various diseases related to respiratory, nervous and circulatory systems.” “Noise pollution is location specific and its intensity declines with increase in distance from the source of pollution, i.e. industrial areas, arteries of transportation, airport, etc.” |
