The Biological Weapons Convention (BWC) was held in:

1972

The correct answer is option (2) - 1972

Disarmament requires all states to give up certain kinds of weapons. For example, the 1972 Biological Weapons Convention (BWC) and the 1992 Chemical Weapons Convention (CWC) banned the production and possession of these weapons. More than 155 states acceded to the BWC and 181 states acceded to the CWC. Both conventions included all the great powers. But the superpowers — the US and Soviet Union — did not want to give up the third type of weapons of mass destruction, namely, nuclear weapons, so they pursued arms control. Arms control regulates the acquisition or development of weapons. The Anti-ballistic Missile (ABM) Treaty in 1972 tried to stop the United States and Soviet Union from using ballistic missiles as a defensive shield to launch a nuclear attack. The US and Soviet Union signed a number of other arms control treaties including the Strategic Arms Limitations Treaty II or SALT II and the Strategic Arms Reduction Treaty (START).
