【正确答案】：B
【题目解析】：细节判断题。题目要求在四项中找出能解释空气污染局势恶化的原因。四个选项分别涉及联邦政府、地方政府、汽车生产商和普通人对待空气污染的态度。文章六至九段分别就这四个方面进行了说明。第六段提到各州和地方政府仍然以罚款作为解决空气污染的手段，而罚款却很少。此外执法不力，补救措施不到位。第七段提到各州未采取定期检查设备的方式来确保有关汽车安装尾气控制设备的法规得以有效执行。第八段提到政府宁愿面对民众的抱怨也不愿面对污染企业的施压。第九段则提到public resentment is …growing.（民怨日甚）。因此，从上下文来看，地方政府的责任最大，所以本题答案为B。
