The correct answers should be A. Bombing more than 60 Japanese cities, C. Declaring a Soviet attack on Japan, and E. Issuing the Potsdam Declaration
The bombing of the cities is often overlooked because of the big two bombs and not many people talk about this. Soviets were preparing to invade occupied pieces of China and free it, as well as attack Hokkaido as it was their deal with allies. The Potsdam declaration was made by the allies in which they requested capitulation of Japan with complete destruction being offered if the declaration was not accepted.
