基于"学生-选课-课程”数据库中的如下三个关系：
学生基本信息：S(S#，SNAME，SEX，AGE)
选课信息：SC(S#，C#，GRADE)
课程信息：C(C#，CNAME，TEACHER)
若要求“查询选修了5门以上课程的学生的学生号”，正确的SQL语句是( )。

A．SELECT S# FROM SC ORDER BY S# WHERE COUNT(*)＞5
B．SELECT S# FROM SC ORDER BY S# HAVING COUNT(*)＞5
C．SELECT S# FROM SC GROUP BY S# WHERE COUNT(*)＞5
D．SELECT S# FROM SC GROUP BY S# HAVING COUNT(*)＞5
