Question: Consider the sample code given below and answer the question that follows.
class Person { public: Person(); virtual ~Person(); }; class Student : public Person { public: Student(); ~Student(); }; main() { Person *p = new Student(); delete p; }
Why is the keyword "virtual" added before the Person destructor?
A
To make it impossible for this particular destructor to be overloaded

B
To ensure that correct destructor is called when p is deleted

C
To ensure that the destructors are called in proper order

D
To improve the speed of class Person's destruction

E
To prevent the Person class from being instantiated directly making it an abstract base class
