Answer: A. The author uses Eckels' fear of the Tyrannosaurus rex to increase the tension of the men being in the past.
In "A Sound of Thunder," the author uses tension to develop the theme of the story by creating a sense of fear and danger throughout the narrative. The tension is primarily built through the character of Eckels, who is fearful of the Tyrannosaurus rex and the dangers of time travel. As the story progresses, the tension increases as the group encounters the massive dinosaur and begins to hunt it. The fear and tension are heightened as the dinosaur begins to attack and the men realize the potential consequences of their actions.
