有如下程序: #inClude<iostream> using namespaCe std; Class Book{ publiC: Book(Char*t=””){strCpy(title,t);} private: Char titlel40]; }; Class Novel:publiC Book{ publiC: Novel(Char*t=””):Book(t){} Char*Category( )Const{return”文学”;} }; int main( ){ Book * pb; pb=new Novel( ); Cout<<pb→Category( ); delete pb; return 0; } 若程序运行时输出结果是“文学”,则横线处缺失的语句是( )。

A.Char*Category( );

B.Char*Category( )Const;

C.virtual Char*Category( )Const;

D.virtual Char*Category( )Const=0;
