The correct answer is option 2: Mutual respect for each other’s territorial integrity and sovereignty, non-aggression, non-interference, equality and mutual benefit, and peaceful co-existence.

Let`s dissect each option to understand why option 2 is the correct answer:

Option 1: This option includes principles such as mutual respect, military collaboration, economic collaboration, decolonization, and territorial integrity. While some of these principles might be important in international relations, they do not fully encompass the principles of peaceful co-existence as outlined by Jawaharlal Nehru.

Option 3: This option includes principles such as peaceful co-existence, economic collaboration, cultural interaction, territorial integrity, and decolonization. Some of these principles align with the principles of peaceful co-existence, but it does not cover all the principles mentioned by Nehru.

Option 4: This option includes principles such as disarmament, peaceful co-existence, economic collaboration, cultural interaction, and territorial integrity. While some of these principles are important, they do not fully encompass the principles of peaceful co-existence as outlined by Nehru.

Therefore, option 2 is the correct answer as it includes all the five principles outlined by Nehru: mutual respect for each other’s territorial integrity and sovereignty
