Which of the following is included in biological attacks?

In the context of biological attacks, the correct response encompasses viruses, bacteria, and biological toxins. Biological attacks specifically refer to the deliberate release of pathogens or toxins to harm or incapacitate individuals or populations.

Viruses and bacteria are the primary infectious agents that can cause diseases, while biological toxins are poisonous substances produced by living organisms. These elements can be weaponized to produce widespread illness and disruption, which aligns with the characteristics of a biological attack.

Chemical agents, explosives, and physical assaults are categorized differently. Chemical agents do not fall under biological weapons, as they involve different methods of harm and effects on humans and the environment. Explosives and toxic gases, while dangerous, denote a different form of attack that does not pertain to biological agents. Physical assaults are acts of violence that are unrelated to the use of biological agents or toxins. Thus, the inclusion of viruses, bacteria, and biological toxins accurately identifies the elements associated with biological attacks.
