Why did many people in Hiroshima believe their city was to be a target?

The city had not had a major attack and expected one.

The city was full of soldiers training to go to war.

The city was a major center for weapons research.

B. The city had not had a major attack and expected one.

Explanation:

First published in 1946, John Hersey's "Hiroshima" tells the story of six survivors of the atomic bomb atack on the city.

All of the survivors spoke about their life before and after bombing, as well as about their thoughts prior to and during the blast.

Also, it is stated that people expected something to happen, because there had been air-rad warnings every day for several weeks, but no bombing, so the people anticipated something big preparing for their city, since all nearby cities have already been severly bombarded.

This can be best seen in the story of the Reverend Mr. Tanimoto.
