1. A

   Vyomesh Chandra, Gopen Chakravartee, Sacheendra Sandal

   (a) claims Vyomesh Chandra, Gopen Chakravartee, and Sacheendra Sandal founded the Hindustan Socialist Democratic Union. However, this combination is historically inaccurate regarding the formation of this specific socialist republican organization.

2. B

   Gopen Chakravartee, Faneendra Banerjee, Dharnee Goswami

   (b) suggests Gopen Chakravartee, Faneendra Banerjee, and Dharnee Goswami as the founders. This option mixes up various revolutionary figures who were associated with different leftist and communist movements rather than the specific party in question.

3. C

   Vyomesh Chandra Banerjee, Ajay Ghosh, Sacheendra Sanyal

   (c) lists Vyomesh Chandra Banerjee, Ajay Ghosh, and Sacheendra Sanyal. Although some of these individuals were prominent freedom fighters, this grouping does not accurately represent the founders of the Hindustan Socialist Democratic Union.

4. D

   Yateendranath, Ayay Ghosh, Phanindranath Ghosh

   (d) identifies Yateendranath, Ajay Ghosh, and Phanindranath Ghosh as the founders of the Hindustan Socialist Democratic Union. This option correctly attributes the formation and involvement of these key revolutionaries associated with the socialist republican movement, making it the accurate choice among the given alternatives.

Summary. Official key is (d) recognising Yateendranath, Ajay Ghosh, and Phanindranath Ghosh in relation to the Hindustan Socialist Democratic Union. Options (a), (b), and (c) incorrectly attribute the foundation to other groups of nationalist and revolutionary figures. Candidates frequently confuse the members of the Hindustan Socialist Republican Association with allied socialist unions. Therefore, option (d) successfully holds as the correct answer based on historical records of the revolutionary movement.
