The first Asian and the only Indian to receive the Nobel Prize in Literature is Rabindranath Tagore. He was awarded the prize in 1913 "because of his profoundly sensitive, fresh and beautiful verse, by which, with consummate skill, he has made his poetic thought, expressed in his own English words, a part of the literature of the West." His notable works include "Gitanjali."
Let's briefly look at the other options:
Bankim Chandra Chatterjee was a prominent Indian novelist, poet, and journalist, known for his novel "Anandamath," which includes the song "Vande Mataram." He was a significant figure in Bengali literature but did not receive the Nobel Prize.
Torudutt was a Bengali poet and writer who wrote in English and French. She is considered one of the first Indian women writers in English, but she passed away at a young age and did not receive the Nobel Prize.
R.K. Narayan was a renowned Indian author known for his works set in the fictional South Indian town of Malgudi. He was a leading figure in early Indian English literature but did not receive the Nobel Prize.
Therefore, Rabindranath Tagore remains the only Indian to have been awarded the Nobel Prize in Literature.
