Explanation
The correct answer is none of the above. The first Republic Day of India was held on January 26, 1950, and the chief guest at that time was not the president of any foreign country, but rather the President of Indonesia, Dr. Sukarno.
The event was attended by various dignitaries, including the Governor-General of India, C. Rajagopalachari, and the Prime Minister of India, Jawaharlal Nehru. However, the most significant guest was President Sukarno of Indonesia, who was invited as a chief guest because of his leadership in the Indonesian independence movement.
Sukarno's presence at the event was seen as a symbol of solidarity between the two newly independent nations, and it helped to establish friendly relations between India and Indonesia. Since then, India has invited various foreign dignitaries to be the chief guest at the Republic Day celebrations, including leaders from countries such as the United States, Russia, and South Africa.
