Solution:These three statements capture accepted principles/objectives of labour welfare and labour legislation.A. Labour legislations were enacted to protect those workers unable to do so on their own: A core principle of labour welfare is protection of the weaker party in employment. Labour law recognises that individual workers usually lack bargaining power, information, and resources, so the State intervenes through legislation to protect them from exploitation and unsafe or unfair conditions.
B. To establish equality in social relationships especially among discriminated groups of labour: Labour welfare also promotes social justice and equality, especially for women workers, scheduled castes/tribes, migrants and other vulnerable groups. Anti-discrimination and equal treatment measures (e.g., Equal Remuneration Act, provisions on non-discrimination in ILO conventions) are grounded in this principle.
C. To regulate workers' organizations from misusing their strengths: Modern labour policy recognises that both employers and worker organisations (trade unions) must be regulated so that their power is used responsibly. Laws on internal democracy. usage of union funds, and rules against coercive or violent tactics reflect the idea that labour welfare includes ensuring unions do not misuse their strength in ways that harm other workers, the public, or the economy.
D. To promote employer efficiency and profit making ability: While labour welfare can indirectly improve efficiency and productivity, the principle is not to promote employer profit as such, but to protect and develop workers. Profit may be a by-product, not the core welfare principle.
E. To nullify international conventions and recommendations ratified by nations: This is the opposite of what labour welfare seeks. Labour standards in India are often influenced by ILO conventions and recommendations, not intended to nullify them.
