The correct answer is option 3, 1835. This is when the British made English the medium of instruction in India. Prior to this, the British East India Company had established English schools in India for the education of their employees` children, but most education in India was still conducted in indigenous languages. However, the decision to make English the medium of instruction was formalized by Lord Macaulay`s minute in 1835. Macaulay argued that English education would create a class of people who would serve as intermediaries between the British and the Indian population. This decision had a profound impact on Indian education and language, as English became the language of privilege and opportunity, while indigenous languages were marginalized.
