The image presents information about biological weapons, including their definition, types, and potential uses. The question asks to identify items that can be used as biological weapons from a given list.
The image explicitly lists "Бактерии" (Bacteria) and "Вирусы" (Viruses) as types of biological weapons. The question also includes "Токсичные химические вещества" (Toxic chemical substances) and "Внутриядерная энергия, выделяющаяся при цепной реакции" (Intranuclear energy released during a chain reaction) as options.
Based on the definition and types of biological weapons presented, bacteria and viruses are directly identified. While toxic chemical substances can be considered as chemical weapons, and intranuclear energy relates to nuclear weapons, the context is strictly about biological weapons. Therefore, only bacteria and viruses fit the category of biological weapons as depicted in the image.
According to the information provided in the image, both bacteria and viruses are classified as biological weapons.
