Assertion (A) : The Central Rural Sanitation Programme was launched in 1986 to improve the quality of life of rural people in India. Reason (R) : Rural sanitation is a subject in the Concurrent List in the Constitution of India.

The correct answer is Option 3 (A is true but R is false).

Assertion (A) is true: The Central Rural Sanitation Programme (CRSP) was indeed launched by the Government of India in 1986. Its primary objective was to improve the quality of life of the rural population and provide privacy and dignity to women through the construction of individual household latrines.

Reason (R) is false: Under the Seventh Schedule of the Constitution of India, "Public health and sanitation" is explicitly listed under Entry 6 of the State List (List II), not the Concurrent List. While the Central Government provides financial and technical assistance through flagship schemes like CRSP, Total Sanitation Campaign, or Swachh Bharat Mission, the primary constitutional responsibility for sanitation lies with the State Governments. Since the Reason (R) is factually incorrect, Option 3 is the only logical choice.
