Q.Nuclear non-proliferation Treaty refers to : (A) Peaceful use of nuclear energy (B) Spread of nuclear weapons (C) Development of nuclear fusion (D) Reduction of nuclear weapons stockpiles

The Nuclear Non-Proliferation Treaty (NPT) is fundamentally about limiting and reducing the number of nuclear weapons in the world. When it was opened for signature in 1968, the treaty had three main pillars: preventing the spread of nuclear weapons to countries that did not already possess them, promoting disarmament among nuclear-weapon states, and ensuring access to peaceful nuclear technology. The disarmament pillar specifically obligates nuclear-weapon states to pursue negotiations in good faith toward reducing and eventually eliminating their nuclear arsenals.

While the treaty does address peaceful uses of nuclear energy, that is a secondary provision meant to ensure non-nuclear states can benefit from nuclear technology for energy and medicine. The core purpose, however, remains the reduction and eventual elimination of nuclear weapons stockpiles held by the recognized nuclear powers. …

The Nuclear Non-Proliferation Treaty, which came into force in 1970, stands as one of the most significant international agreements in the post-World War II era. Its creation reflected a world deeply anxious about the unchecked growth of nuclear arsenals during the Cold War. The treaty rests on three interconnected pillars: non-proliferation (preventing the spread of nuclear weapons to countries that do not possess them), disarmament (requiring nuclear-armed states to work toward reducing and eventually eliminating their stockpiles), and the right to peaceful nuclear technology.

While the treaty does address multiple dimensions of nuclear policy, its central thrust has always been disarmament. The five recognized nuclear-weapon states under the NPT—the United States, Russia, the United Kingdom, France, and China—committed themselves explicitly to pursue negotiations in good faith toward nuclear disarmament. This obligation distinguishes the NPT from a mere freeze or containment agreement; it envisions a progressive reduction of existing arsenals, not simply their maintenance at current levels.

Option (A), peaceful use of nuclear energy, is indeed part of the treaty's framework—signatories retain the right to develop nuclear technology for energy, medicine, and research. However, this is a secondary provision designed to balance the restrictions on weapons development, not the treaty's defining purpose.

Option (B), the spread of nuclear weapons, captures what the treaty seeks to prevent rather than what it refers to. Non-proliferation is the mechanism, but the ultimate goal extends beyond simply halting horizontal spread to include vertical reduction among existing nuclear powers. …
