Correct Answer: (b) Chitranjan Das
Solution:Chittaranjan Das, a revolutionary freedom fighter, was endearingly called 'Deshabandhu' (Friend of the Nation). Das was a lawyer by profession and made a name for himself when he returned to India after finishing his studies abroad, took up a law practice and defended Sri Aurobindo Ghose in a court suit filed against him. After the failure of the Non-cooperation Movement, he became disillusioned and proposed a strategy to end dyarchy, but Congress did not accept it. He formed his own party, Swaraj Party, along with Motilal Nehru.
