Who among the following were the founders of the "Hind Mazdoor Sabha" established in 1948?

1. A

   B. Krishna Pillai, E.M.S. Namboodiripad and K.C. George

   (a) B. Krishna Pillai, E.M.S. Namboodiripad and K.C. George. These names belong to Kerala communist politics, not to the 1948 founding of Hind Mazdoor Sabha. This option is not the key.

2. B

   Jayaprakash Narayan, DeenDayal Upadhyay and M.N. Roy

   (b) Jayaprakash Narayan, Deendayal Upadhyay and M.N. Roy. A mixed set from socialist, Jana Sangh and Radical Humanist streams; they were not the HMS founding trio asked. This option is not the key.

3. C

   C.P. Ramaswamy Iyer, K. Kamaraj and Veeresalingam Pantulu

   (c) C.P. Ramaswamy Iyer, K. Kamaraj and Veeresalingam Pantulu. A Dewan, a Congress Tamil leader, and a 19th-century social reformer—not HMS founders. This option is not the key.

4. D

   Ashok Mehta, T.S. Ramanujan and G.G. Mehta

   (d) Ashok Mehta, T.S. Ramanujan and G.G. Mehta. Hind Mazdoor Sabha was formed in December 1948 by socialists including Ashok Mehta, T.S. Ramanujam and G.G. Mehta (with others such as R.S. Ruikar). That is the stored set. This option is the official key.

Summary. Official key is (d) Ashok Mehta, T.S. Ramanujan and G.G. Mehta. HMS was a non-communist national trade-union centre launched in 1948 from the socialist stream. The other name-lists belong to Kerala communism, mixed all-India figures, or unrelated South Indian leaders. Only (d) matches the founding trio in the options. That is the Set A key.
