The correct answer is option 3, Panchayati Raj. The Balwant Rai Mehta Committee was a committee appointed by the Government of India in 1957 to examine the functioning of the Community Development Program and the National Extension Service. The committee was named after its chairman, Balwant Rai Mehta. The committee`s main focus was on decentralization of powers and strengthening local self-government institutions in rural areas. The committee`s recommendations formed the basis for the Panchayati Raj System, which was later implemented in India. This system aimed to empower local communities and give them greater control over their own development by establishing elected village panchayats and providing them with the necessary resources and authority to undertake local governance and development activities.
