I think it's B because the narrator was excited to aboard the plane for the war but towards the end he slowly starting recognizing that we are in war and we are trying to save the county so it's a serious thing.
B.the author once felt pride and optimism about the war.
In the passage the author talks about how he was proud of the American pilots and grateful to bear witness. He speaks about he feels that the war efforts will bring about "a better country". We do not know if this was the author's first flying experience. There is nothing mentioned about hand-to-hand combat for US soldiers. We also don't know if the author has any begrudging respect for the Vietcong.
