An initiative to strengthen Gram Panchayats in Karnataka:

Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA)
Swachh Bharat Mission
Pradhan Mantri Awas Yojana
Gram Swaraj Abhiyan

The correct answer is: D) Gram Swaraj Abhiyan

Gram Swaraj Abhiyan is a government initiative to strengthen Gram Panchayats in Karnataka. It was launched in 2014 with the objective of making Gram Panchayats more effective and accountable to the people. The Abhiyan aims to achieve this by providing training and capacity building to Gram Panchayat members, strengthening the financial and administrative systems of Gram Panchayats, and promoting citizen participation in local governance.

Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) is a national employment guarantee scheme that provides rural households with the right to demand 100 days of paid work in a year. The scheme was launched in 2005 with the objective of providing employment and income security to the rural poor.

Swachh Bharat Mission is a national cleanliness campaign that was launched in 2014 with the objective of making India a clean and open defecation-free country. The campaign aims to achieve this by constructing toilets, promoting cleanliness and hygiene, and creating awareness about the importance of sanitation.

Pradhan Mantri Awas Yojana is a national housing scheme that was launched in 2015 with the objective of providing affordable housing to the poor. The scheme aims to achieve this by providing financial assistance to eligible households to construct or purchase a house.

Gram Swaraj Abhiyan is a more recent initiative than the other three options and is specifically focused on strengthening Gram Panchayats. The other three options are national-level schemes that have a broader scope.
