Statements 1 and 2 are correct. The Biological Weapons Convention (BWC) explicitly prohibits the development, production, acquisition, transfer, stockpiling, and use of biological and toxin weapons for hostile purposes. It aims to eliminate this category of weapons of mass destruction.  The BWC is legally binding on its member states; however, it lacks a formal verification regime to monitor compliance or enforce its provisions. States Parties rely on confidence-building measures and domestic implementation to ensure adherence to the treaty.
