Near the city of Yogyakarta in Java（爪哇岛）is not only one magnificent（宏伟的）monument, Borobudur（婆罗浮屠）, but a second equally impressive one. Prambanan, the second monument, shares a remarkable number of things in common with Borobudur.First, both huge temple complexes (建筑群) are thought to have been built at about the same time, around 850 AD. 【1】 Some historians think that both temples were created during the era of the Sailendra DynastySecond, in both cases, the temples appear to have been abandoned just after they were completed. Why were they left alone, 一种白色固体可能由Na+、Ba2+、Cl-、Br-、HCO3-、SO3-、SO4-离子中的若干种组成,陶宝同学设计实验检验其组成,记录如下: 步骤 实验操作 实验现象 ① 将固体溶于水,用pH试纸检验 无色溶液pH=9 ② 向溶液中滴加氯水,再加入CCl4振荡,静置 产生气泡,CCl4层呈橙色 ③ 向②所得水溶液中加入Ba(NO3)2溶液和稀HNO3 有白色沉淀产生 ④ 过滤,向滤液中加入AgNO3溶液和稀HNO3 有白色沉淀产生 下列关于固体组成的结论错误的是        (　　) A.肯定含有Br-,可能含有HCO3- B.至少含有SO3-、SO4-中的一种离子 C.肯定不含Ba2+,一定含有Cl- D.无需焰色反应即可断定溶液中含有Na+
