Final answer:
The most common type of Weapon of Mass Destruction is nuclear. Nuclear weapons, which include fission and thermonuclear bombs, utilize nuclear reactions to unleash immense destructive power, exceeding that of other types of weapons of mass destruction such as chemical and biological weapons.The correct option is c.
Step-by-step explanation:
The most common type of Weapon of Mass Destruction (WMD) is nuclear. Nuclear weapons are explosive devices that derive their destructive power from nuclear reactions, primarily fission and sometimes a combination of fission and fusion.
There are two main types of nuclear weapons: fission bombs, which utilize fission alone, and thermonuclear bombs, which use fission to ignite fusion.
The process of a fission bomb involves bringing together two separate lumps of fissile material such as highly enriched uranium (235U) or plutonium (239Pu) to achieve a critical mass and initiate an uncontrolled chain reaction, leading to a massive explosion. The development and proliferation of these nuclear weapons have been a key focus of modern foreign policy challenges.
While chemical and biological weapons also represent significant threats, their impact is generally considered to be smaller in comparison to that of a nuclear war, which can result in immense destruction and loss of life. The correct option is c.
