如果A为整数且|A|>=100.则打印OK,否则打印Error,表示这个条件的单行格式If语句是()
A.:If Int(A)=A And Sqr(A)>=100 Then Print OK Else Print Error B.:If Fix(A)=A And Abs(A)>=100 Then Print OK Else Print Error C.:If Int(A)=A And (A>=100,A<=-100) Then Print OK Else Print Error D.:If Fix(A)=A And A>=100 And A<=-100 Then Print OK Else Print Error
