Complete answer:
First of all we need to know about nuclear weapons. It is nothing but a device designed to release energy in the manner of explosion as a result of nuclear fission, nuclear fusion or a combination of the two processes.
A nuclear weapon of first test is occurred in the United States on July 16, 1945 at Alamogordo bombing in south-central in New Mexico. This test was named by Trinity.
Nuclear weapons produce explosive energy. Its significance is best appreciated by the coining of words kiloton and megaton to describe their blast energy. And it is the equivalent weight of conventional chemical explosion.
Let's talk about the effects of nuclear weapons. There are some weapons of nuclear destruction such as blast, thermal radiation, and prompt ionizing radiation which can cause a significant destruction within a seconds or minutes of a nuclear destruction. There are also some delayed effects such as radioactive fallout, environmental effects and inflict damage through an extended period ranging from hours to years.
A nuclear holocaust also called as a nuclear apocalypse, nuclear Armageddon or atomic holocaust. In theory where the mass detonation of nuclear weapons caused globally a wide range of spread destruction.
Thus the largest scale destruction that is caused due to the use of nuclear weapon is known as nuclear holocaust.
Hence, the correct answer is option A





Note:Nuclear weapons are used for the dangers from such weapons raised from their existences. And also nuclear weapons have only used in twice in warfare in the bombings of Hiroshima and Nagasaki about 13,400 remains in our world today. And there have been over 2000 nuclear tests conducted.
The result of a nuclear war, especially one involving widespread destruction of our life and the whole environment of the world.
