I have been asked this question in an interview for internship.

Answer 1

Right option is (d) It can only store object address of class type specified

Explanation: The address of only the specified class type can get their address stored in the object pointer. The addresses doesn’t differ but they do differ for the amount and type of memory required for objects of different classes. Hence same class object pointer should be used.
