Correct Option
Assertion (A) is true. The Central Rural Sanitation Programme (CRSP) was launched in 1986 by the Government of India. Its objective was to improve the quality of life of rural people by promoting better sanitation facilities, reducing open defecation, and enhancing public hygiene. This initiative represented India's first national-level effort towards organized rural sanitation.
Reason (R) is false. According to the Seventh Schedule of the Constitution of India, 'Public Health and Sanitation' is enumerated under the State List (List II, Entry 6). Therefore, rural sanitation, being an integral part of public health and sanitation, falls within the exclusive legislative competence of state governments, classifying it as a State subject, not a Concurrent subject.
Since Reason (R) is factually incorrect, it cannot provide a correct explanation for Assertion (A).
Incorrect Options
Options (a), (b), and (d) are incorrect because they are based on an erroneous assessment of either Assertion (A) or Reason (R). Option (a) and (b) incorrectly state that Reason (R) is true. Option (d) incorrectly states that Assertion (A) is false. The correct evaluation establishes that Assertion (A) is true and Reason (R) is false.
