The correct answer is option 2 "1951-52". The first General Election to the Lok Sabha, which is the lower house of the Indian Parliament, was conducted in 1951-52. It is important to note that India adopted the Constitution on January 26, 1950, but the first General Election was held one year later. This election marked a historic moment as it was the first time that eligible Indian citizens had the opportunity to choose their representatives in a democratic manner. The election process was conducted in multiple phases across the country to ensure participation from all regions. It played a crucial role in shaping the democratic fabric of India and establishing the Lok Sabha as the representative body of the people.
