定义结构体后，定义变量、数组赋值正确的是（）数据结构里，struct student{char name【20】;char sex【10】;int age;int score;}

A.struct student s={"张三","男",18,100}

B.struct student stu[3]={{ ""张三"",""男"",18,100},{ "李四","男",19,90},{ "王五","男",23,97} }

C.struct student s={"李四";"女";18;100}

D.struct student stu[3]={{ "张三",18,"男",100},{ "李四",19,"男",90},{ "王五",23,"男",97} }
