下面的描述中，（ ）不能正确定义一个名为 Student 的结构体以及一个包含20个元素的结构数组。
- A. 1 struct Student { 2 string name; 3 int age; 4 float score; 5 }; 6 struct Student students[20];
- B. 1 struct Student { 2 string name; 3 int age; 4 float score; 5 }; 6 Student students[20];
- C. 1 struct Student { 2 string name; 3 int age; 4 float score; 5 }; 6 Student* students = new Student[20];
- D. 1 struct Student { 2 string name; 3 int age; 4 float score; 5 }; 6 Student students = new Student[20];
正确答案：D
