The correct answer is (a) 1885.
The Indian National Congress (INC) was founded on December 28, 1885, in Bombay, British India (now Mumbai, India). It was founded by Allan Octavian Hume, a retired British civil servant, who wanted to create a forum for educated Indians to discuss their grievances and work towards self-government. The INC’s first president was Womesh Chandra Bonnerjee.
The INC initially focused on social reform and education, but it soon became involved in the independence movement. In 1906, the INC adopted the goal of swaraj, or self-rule. The INC played a leading role in the Indian independence movement, and its leaders, including Mahatma Gandhi and Jawaharlal Nehru, were instrumental in the country’s eventual independence in 1947.
The INC has continued to be a major political party in India since independence. It has been in power at the national level for several periods, most recently from 2004 to 2014. The INC is a member of the Socialist International.
The other options are incorrect because the INC was not founded in those years.
