Hint: People who are seen as less important or inconsequential, as well as those who are considered to be of lower status, are referred to as marginalised. They are regarded as untouchables by some elements of Indian society. There are a variety of reasons why marginalised persons are treated in this manner. One of the reasons they are treated this way is that the people in authority regard their contributions to society as insignificant.
The Indian constitution recognises socially marginalised populations based on caste. We can also find marginalisation on the basis of gender, disability, and caste in India. The Indian constitution contains numerous measures aimed at preventing social marginalisation.
The promotion of the educational and economic interests of the weaker parts of the population, particularly the Scheduled Castes and Scheduled Tribes, is mentioned in Article 46 of the Indian Constitution. It also refers to the defence of vulnerable groups against all sorts of exploitation and social injustice. States will be required to promote and preserve the educational and economic interests of Scheduled Castes and Scheduled Tribes under Article 46 of the Indian Constitution. It will safeguard Scheduled Castes and Tribes against all types of exploitation and social injustice. Article 46 of the Constitution of India refers to the promotion of educational and economic interests of scheduled Castes, Scheduled Tribes and other weaker sections.
Thus, the correct option is, (B) Scheduled Castes, Scheduled Tribes and other weaker sections.
Note: Article 46 is exclusively defined in Part IV, which is under Directive Principle of State Policy(DPSP). That means the government has full authority for its implementation. However, if the government is unable to implement it properly, you can not go to the Supreme Court against the state to file a charge sheet. The DPSPs are referenced in the constitution because they clarify the state's ideals. Regardless of which party forms the government, it is only responsible for the policies outlined in the constitution.
