Option 1: Mahatma Gandhi is not called the ‘Father of the Indian National Congress’. Although he played a crucial role in the Indian independence movement, the Indian National Congress was founded before Gandhi`s active involvement.

Option 2: A.O. Hume is correctly called the ‘Father of the Indian National Congress’. He was a British civil servant who played a significant role in the establishment of the Congress in 1885. Hume acted as the secretary of the party and worked towards mobilizing Indians against British rule.

Option 3: Lokmanya Tilak, while an important figure in the Indian independence movement, is not called the ‘Father of the Indian National Congress’. Tilak was a prominent leader and nationalist, known for his efforts in uniting people against British rule.

Option 4: Surenra Nath Bannerjee, although an influential leader in the early years of the Indian National Congress, is not called the ‘Father of the Indian National Congress’. A.O. Hume is attributed with this title.

Therefore, the correct answer is option 2, A.O. Hume.
