选项 A、not using air-condition and opening the windows
B、cutting energy costs and letting the air in
C、using routine maintenance of HVAC systems
D、not working in office buildings
答案 C
解析 根据题干信息词the EPA，recommend和sick定位到第六个小标题下的最后一句。文章提到美国环保署 (EPA)估计美国大约有30%的办公楼是有问题的，所以他们(美国环保署)建议对采暖通风和空调系统进行日常维护，故答案为C。
