This discussion explores the possibility of registering a single NGO under various Indian acts, including the Indian Trust Act, Societies Act, Companies Act (Section 8), and Income Tax Act. While generally permissible if the NGO's functioning aligns with each act's stipulations and doesn't contravene other laws, the initial response highlights a lack of clarity in the original question. It suggests that registration under the Societies Registration Act, 1860, is a common route for establishing an NGO.
