已知下面代码，则选项中最可能不合理的是： class Car { public: Car( ){ /*略*/ } void doFunc( ) { /*略*/ }; //其它略 }; class MTCar:public Car { public: MTCar( ){ /*略*/ } void newFunc( ){ /*略*/ } //其它略 }; class Foo { public: Foo(Car * pobj=nullptr):mp(pobj){ } void func(Car & obj){ obj.doFunc( ); } private: Car * mp; //其它略 };
选项：

A:MTCar mc; Foo fobj(&mc);
B:MTCar mc; Foo fobj; fobj.func(mc);
C:MTCar mc; Car *pc=(Car*)(&mc);
D:Car c;
MTCar* pmc=(MTCar*)(&c);
E:MTCar mc; Car c; c=mc;
