选项
答案 A
解析 冷藏对环境的破坏带来的风险会导致什么。题干关键词为environmental devastation，通过做之前的题目，也可以大概猜到这里说的对环境破坏就是指氟利昂对臭氧层破坏。剩下的两个选项定位词很明显分别为Hydrofluorocarbons和chlorofluorocarbons(Freon)，都出现于原文最后1段，扫读这两个词出现位置的描述。原文在提到氟利昂会对臭氧层造成破坏之后说，又找到了新的替代物质用于冷藏，目前没有发现危害。其中new improvements对应A选项new developments。而C选项氟利昂发现的原因则是因为Frigidaire公司为找到一种新的合成制冷剂进行了一项研究。因此，本题的答案为A。
