    正确答案：C
    try－catoh块是可以嵌套分层的，并且通过异常对象的数据类型进行匹配，以找到正确的catchblock异常错误处理代码。以下是通过异常对象的数据类型进行匹配找到正确的catchblock的过程。①首先在抛出异常的try－catch块中查找catchblock，按顺序先与第－个catchblock块匹配，如果抛出的异常对象的数据类型与catchblockee传入的异常对象的临时变量(就是catch语句后面参数)的数据类型完全相同，或是它的子类型对象，则匹配成功，进入catchblock中执行，否则到第②步；②如果有两个或更多的catchblock，则继续查找匹配第二个、第三个，乃至最后－个catchblock，如匹配成功，则进入对应的catchblock中执行，否则到第③步；③返回到上－级的try-catch块中，按规则继续查找对应的catchblock。如果找到，进入对应的catchblock中执行，否则到第4步；④再到上上级的try-catch块中，如此不断递归，直到匹配到顶级的try－catch块中的最后－个catchblock，如果找到，进入到对应的catchblock中执行；否则程序将会执行terminate（）退出。所以选C。
