The three primary effects of an explosion are

Blast, fragmentation, incendiary/thermal
Blast, earthquake, incendiary/thermal
Fragmentation, pulse, blast
None of the above

The correct answer is: Blast, fragmentation, incendiary/thermal

The primary effects of an explosion are commonly identified as blast, fragmentation, and incendiary/thermal effects. The blast effect refers to the pressure wave created by the rapid expansion of gases during an explosion. This wave can cause significant destruction to buildings and can also result in injury or death to individuals in proximity to the explosion. Fragmentation is the result of the explosion causing materials that are nearby to become projectiles. These fragments can travel at high velocities, posing additional harm to people and property in the vicinity. Incendiary or thermal effects relate to the intense heat generated by an explosion. This can ignite fires and cause burns to individuals who are exposed to this heat, contributing to the overall danger of an explosive incident. The other choices do not accurately represent the fundamental effects of an explosion, as they either include unrelated terms or omit the critical elements in understanding how explosive forces impact the environment. Thus, the combination of blast, fragmentation, and incendiary/thermal effects highlights the significant risks and damage associated with explosions.
