下列句子中，没有语病的一句是______。

A．政府机关所有工作人员都必须认真遵守国家的法律、法规和政策，忠实履行自己的职责

B．经过调查研究，广泛征求意见，我们已拟订了国务院机构的改革方案，并将提交本次大会审议

C．如何防备展览会的展品和珠宝店里的贵重物品免遭盗窃，是安全保卫部门深感头痛的一件事

D．这种将企业各方的权利义务用合同形式加以明确，对于职工行使民主管理权利无疑是一种保障

答案

参考答案：B

解析： A项属于单项与多项搭配不当，“遵守”“法律、法规”可以，但不能“遵守”“政策”，应该是“执行政策”。C项属于不合逻辑，“防备……免遭”是矛盾的。D项属于成分残缺，“是一种保障”没有主语中心词，应在“明确”后加“的做法”。
