【答案解析】[听力原文]
   M: Please move forward, people, and have your boarding pass and picture ID ready for inspection. No liquids of any kind will be permitted past the inspection point, including liquid cosmetics and drinks. If you are carrying any liquids, you will need to throw them away before you pass the screener. Also, if you're carrying a laptop, you will need to remove it from your carry-on, open it and pass it separately through the screener. Also, if any of you prefer not to pass the body scanner, you will have to submit to a pat-down inspection. We appreciate your cooperating with security regulations so that we can get you all to your gates as quickly as possible and on time for your flights. Have a nice day.
选项A错误，body scanner是指安检用的“人体扫描仪”，不是医疗检查设备。选项B正确。选项C和D错误，情境是面临机场安检。
