Part A: The author describes the dangerous situation that the characters in the story are facing.
Throughout the passage the speaker reminds the reader of the danger the characters are facing. This creates suspense. A flashback does not create suspense. The background and training adds to how dangerous the situation is since only a person that well-trained can complete the rescue but it doesn't add to the suspense: the danger does. A is also wrong for the same reason.
Part B: “I shouldn’t think of this as easy. I know what I need to do here, but I could lose one these men if just one thing goes wrong.”
This quote best shows the danger that the speaker and the characters are in. It shows that the situation is life and death. One wrong move and it's all over for someone.
