The correct option is D Jawahar Lal Nehru
Jawaharlal Nehru wrote in Discovery of India, “The scientific approach and temper are, or should be, a way of life, a process of thinking, a method of acting and associating with life, a process of thinking, a method of acting and associating with our fellowmen.” Following Nehru’s vision, the Indian Parliament adopted the Scientific Policy Resolution (SPR) of 1958, which enunciated the principles on which the growth of science and technology would be based. Hence, Nehru pioneered the assimilation of scientific temper among masses in India.
