选项 A、using home-made electrical goods
B、wearing clothes made of natural materials
C、walking on artificial floor coverings
D、sorting food in a refrigerator
答案 C
解析 推理判断题。根据第一段最后一句话，这种static electricity(静电)可能来源于地毯，人造纤维衣物，电视，复印机和电脑显示器。据此可以推断接触上述物品可以产生静电，因此选C。A.“使用家用电器”，犯了以偏概全的毛病；B.“穿着天然材质的衣物”，不会引起静电；D.“对冰箱食物进行分类”，文章未提及。
