Which statement about suicide bombs or bombers is TRUE?

The statement regarding suicide bombers potentially carrying chemical or biological hazards is accurate because, in certain situations, attackers may attempt to utilize these materials to enhance the lethality or impact of their attacks. While conventional explosives remain the most common method, the inclusion of chemical or biological agents poses a significant risk due to their ability to inflict harm on a larger scale, complicating response efforts and increasing public fear.

The complexity and expense of creating suicide bombs vary based on the materials used, and while some bomb-making methods can be intricate, many improvised explosive devices (IEDs) can be made with relatively accessible materials. Additionally, the intent of suicide bombers often encompasses causing mass casualties, which may include bystanders, contrary to the notion that they do not aim to harm others. Finally, the effectiveness of suicide bombings has been evidenced historically as they have resulted in significant injuries and chaos, contradicting the idea that they are ineffective.
