In the Kanpur Bolshevik conspiracy case in 1924, it was the individuals mentioned in option 1, namely Muzaffar Ahmad, S. A. Dange, Shaukat Usmani, and Nalini Gupta, who were jailed.

Option 2 states that Muhammad Ali and Shaukat Usmani were jailed, which is not correct as Nalini Gupta was also involved.

Option 3 states that S. A. Dange and S. V. Ghate were jailed, which is incorrect as Shaukat Usmani and Nalini Gupta were also among those jailed.

Option 4 mentions Muzaffar Ahmad and S.S. Mirajkar, which is not accurate as it does not include S. A. Dange and Shaukat Usmani.

Therefore, option 1 is the correct answer as it lists all the individuals who were imprisoned in the Kanpur Bolshevik conspiracy case in 1924.
