Detailed Solution:
The correct answer is “M.A. Ansari”.
M.A. Ansari was NOT associated with the Kanpur Conspiracy Case of 1924.
He was a prominent Indian Muslim leader and a member of the Khilafat Movement, but he was not involved in the communist-led conspiracy. Muzaffar Ahmed, Nalini Gupta, and Shaukat Usmani were all key figures in the case.
The Kanpur Bolshevik Conspiracy Case was a controversial court case in British India in 1924 that charged a group of communists with conspiring against the government.
