UPSC NDA-1 – 2015
The correct answer is D) G V Apparao.
Jaya Prakash Narayan, Acharya Vinoba Bhave, and Dhirendra Mazumdar were prominent figures actively involved in the Sarvodaya movement and its related activities like the Bhoodan and Gramdan movements, inspired by the principles of Mahatma Gandhi. G V Apparao (Gurajada Apparao) was a renowned Telugu writer and social reformer from Andhra Pradesh, known for his literary works and efforts against social evils, but he is not primarily associated with the Sarvodaya movement led by Gandhians like Vinoba Bhave and JP Narayan.
The Sarvodaya movement aims for the welfare of all (sarva=all, udaya=uplift). It is based on Gandhian principles of non-violence, self-sufficiency, and social justice, seeking a non-violent social revolution. Key figures associated with it include Mahatma Gandhi, Vinoba Bhave (who led the Bhoodan-Gramdan movement as a follow-up to Sarvodaya ideals), and Jaya Prakash Narayan (who played a significant role, especially in the later phase and related political movements).
