The correct answer is option 3, 1951. The first General Election in India was conducted in 1951, where Indian citizens had the opportunity to vote and elect their representatives to the Lok Sabha (the lower house of Parliament) and the State Legislative Assemblies. This election was held under the provisions of the Indian Constitution, which was adopted in 1950. The first Amendment to the Constitution, which introduced several changes and modifications, including the abolition of titles and privy purses, was also made in 1951. Therefore, option 3, 1951, is the correct answer as it correctly identifies the year when both the first General Election and the first Amendment to the Constitution took place.
