This is tricky. It could be either A or D. It would definitely have to do with buying war bonds, but it also has to do with helping in whatever way you can for the war (i.e. Not eating bread on certain days, working extra hours building missiles, buying war bonds, etc.) because buying war bonds is more specific than just "helping out in whatever way", I would say that it is A.
Hope I helped! :) (would you mind giving Brainliest? I'm trying to increase my title. I'd really appreciate it!)
Answer: Hue
The Battle of Hue (or Massacre of Hue) is considered one of the bloodiest events of the war. It started on January 31, 1968 and lasted for 26 days. During the capture and occupation of the city by the Viet Cong and the People's Army of Vietnam, a huge amount of executions and mass killings took place. The death toll is estimated to be between 2,800 and 6,000 civilians and POWs.
I personally believe that no one is born with prejudices.
We all form our own opinions based on our own experiences. But all prejudice is influenced by family, friends, peers, and anyone else you interact with.
