D. It is expected that the majority of students entering the law school this fall are expected to be women, a trend ultimately placing

A   错误在于placing，placing(-ING结构)表示place这个动作和women are expected是同时发生的；根据独立主格结构的语法规则，只有当抽象名词可以作为-ING的主语时， 才可以将此抽象名词转换为-ING结构的独立主格结构。而在此题中，“trend” 不可以作为 “placing” 的主语，所以错误。
B   正确✅。根据独立主格结构的语法规则，“trend” 作为一个抽象名词可以指代前面的句子（The majority of students entering law school this fall are expected to be women）。
