有学生表Student(S# char(8), Sname char(10), Ssex char(2), Sage integer, D# char(2), Sclass char(6))。要检索学生表中“所有年龄小于等于19岁的学生的年龄及姓名”,SQL语句正确的是( )。
选项:
A:Select * From Student Where Sage <= 19;
B:Select Sname From Student Where Sage <= 19;
C:Select Sage, Sname From Student Where Sage <= 19;
D:Select Sage, Sname From Student;
