The correct answer is option 3: 1813. The Charter Act of 1813 was a significant legislation passed by the British Parliament, which had an impact on education in India. Prior to this act, education in India was mainly provided by private institutions and religious bodies. However, the Charter Act of 1813 introduced a new provision that allocated a specific amount of money from the East India Company`s funds for the promotion and development of education in India.

Option 1, 1773, is incorrect because the Charter Act of 1773 did not make any provisions for financial allocation for education. Option 2, 1793, is also incorrect as there was no specific mention of financial allocation for education in the Charter Act of 1793. Option 4, 1833, is also incorrect as the Charter Act of 1833 focused more on other aspects of governance and administration, rather than education.

Therefore, the correct answer is option 3: 1813, as it was the Charter Act that introduced the first financial allocation for education in India.
