What catastrophic effect did the bomb dropped on Hiroshima on August 6, 1945, have on its victims?

The bomb dropped on Hiroshima on August 6, 1945, produced intense heat and radiation that caused severe burns and radiation poisoning among its victims. The explosion produced temperatures exceeding 1,000 degrees Celsius within seconds, leading to horrific thermal injuries. Many victims suffered from first, second, and third-degree burns over large portions of their bodies. Additionally, the radiation emitted from the bomb resulted in acute radiation syndrome in many survivors, manifesting symptoms like nausea, vomiting, and a compromised immune system, which ultimately led to long-term health consequences, including increased cancer risk.

While the other options may describe potential effects in different contexts, they do not accurately capture the specific and immediate consequences experienced by the people of Hiroshima following the atomic bombing. The severity and immediate nature of the burns and radiation effects were defining characteristics of this catastrophic event.
