Correct answer: B. Aligarh
Explanation: The direct answer is B: Aligarh. MAO College means Muhammadan Anglo-Oriental College, founded by Sir Syed Ahmad Khan in Aligarh in 1875. It later developed into Aligarh Muslim University. The college aimed to provide modern education, including English and scientific learning, while also addressing the educational needs of Muslims. Step by step: Sir Syed promoted educational reform; he established the college; the institution was located in Aligarh; it became an important centre of the Aligarh Movement. Option B is correct because the city and institution share the name Aligarh. Option A, Banaras, was not the location of MAO College. Option C, Lucknow, was an important historical and educational city but not the answer here. Option D, Patna, was also not its location. Memory cue: MAO College → Aligarh → later Aligarh Muslim University.
