The correct answer is option 3, Pandit Jawaharlal Nehru. The Panchsheel principles were propounded by Pandit Jawaharlal Nehru, who was the first Prime Minister of India. These principles were a set of five principles for peaceful coexistence between nations. They were first formally adopted by India and China in an agreement known as the Agreement on Trade and Intercourse between Tibet Region of China and India. The principles include mutual respect for each other`s territorial integrity and sovereignty, non-aggression, non-interference in each other`s internal affairs, equality and mutual benefit, and peaceful coexistence. These principles aim to promote peaceful relations and resolve conflicts through dialogue and negotiation, rather than through the use of force.
