若给出关系Student(S_no,Sname,Sage,S_sex,SD_name,S_add,S_tel)，并用SQL语言定义Student关系如下：
CREATE Student(S_no CHAR(6),
Sname CHAR(30) NOT NULL,
Sage CHAR(30),
S_sex CHAR(1),
SD_name CHAR(20),
S_add CHAR(30),
S_tel CHAR(20),
PRIMARY KEY(S_no))
以下哪条记录插入到Student表能被正确地执行______。
A．INSERT INTO Student(S_no,Sname,Sage,S_sex,SD_name,S_add,S_tel)
VALUES(’010456’,’小芳’,’18’,",",",")
B．INSERT INTO Student(S_no,Sname,Sage,S_sex,SD_name,S_add,S_tel)
VALUES(’010456’,’小芳’,’18’,’女’,’计算机学院’,’北京’,’88661200’)
C．INSERT INTO Student(S_no,Sname,Sage,S_sex,SD_name,S_add,S_tel)
VALUES(’小芳’,’18’,’F’,’计算机学院’,’北京’,’88661200’)
D．INSERT INTO Student(S_no,Sname,Sage,S_sex,SD_name,S_add,S_tel)
VALUES(’010456’,,’18’’F’,’计算机学院’,’北京’,’88661200’)
