The correct answer is Option 2- Rabindranath Tagore

Rabindranath Tagore, a renowned Bengali poet, writer, and philosopher, was awarded a knighthood (Knight Bachelor) by the British Raj in 1915. However, in 1919, following the horrific Jallianwala Bagh massacre, he renounced this honor as a symbolic act of protest against the British brutality.
