The correct answer is option 3: Kolkata. The National Anthem of India, "Jana Gana Mana," was first sung in the year 1911. It was performed at the Annual Session of the Indian National Congress, which was held in Kolkata. The song, written by Rabindranath Tagore, was originally a Bengali poem, which was later set to music and adopted as the National Anthem of India. It is important to note that Kolkata, previously known as Calcutta, played a significant role in India`s independence movement and was a hub for political and cultural activities during that time. Therefore, the first singing of the National Anthem was an important event held in Kolkata as part of the Indian National Congress session.
