现有学生信息表Student_info,其中包括姓名(stu_name),学号(stu_id),成绩(stu_grade).我们需要查询成绩为80分的学生姓名，要求结果按照学号降序排列。
下面SQL查询语句正确的是

A.SELECT stu_id, stu_name FROM student_info WHERE stu_grade=80 ORDER BY stu_name ASC

B.SELECT stu_name FROM student_info WHERE stu_grade=80 ORDER BY stu_id DESC

C.SELECT stu_id, stu_name FROM student_info WHERE stu_grade=80 ORDER BY stu_name ASC

D.SELECT stu_name FROM student_info WHERE stu_grade LIKE 80 ORDER BY stu_id DESC
