Explanation:

The Non-Cooperation Movement (1920-1922) was a pivotal phase in the Indian independence struggle, led by Mahatma Gandhi. While many prominent leaders joined, **Annie Besant** was notably *not* a part of it. A leading figure of the Theosophical Society and the Home Rule League, Besant believed in constitutional methods and opposed Gandhi's non-cooperation strategy, which she viewed as anarchic and detrimental to the cause of self-government. She advocated for continued engagement with the British government through constitutional means. Option B is correct. M.A. Ansari (Option A), Abul Kalam Azad (Option C), and Hakim Ajmal Khan (Option D) were all prominent Muslim leaders who actively participated in and strongly supported the Non-Cooperation Movement. They were key figures in the Khilafat Movement, which merged with the Non-Cooperation Movement, and played crucial roles in mobilizing support for Gandhi's call for non-violent resistance and boycott of British institutions.
