3. C

   A-(1), B-(3), C-(2), D-(4)

4. D

   A-(4), B-(1), C-(3), D-(2)

   Option (d) correctly matches Bharatiya Mazdoor Sangh with Bharatiya Janata Party, Indian National Trade Union Congress with Indian National Congress, United Trade Union Congress with Communist Party of India (Marxist), and All India Trade Union Congress with Communist Party of India.

This question tests the knowledge of prominent trade union federations and their historical or ideological political linkages in India. Students often confuse the affiliations of various communist and socialist trade unions due to multiple splits over decades. Careful verification of central trade union origins resolves these confusions completely. Option (d) successfully integrates all correct pairs without any error. Hence, this option remains the only valid choice.
