Q3[C++11]: Which of the following statements about inheriting base class constructors is false?

Q:
Q2: Which statement about class unique_ptr (of the new C++ standard) and dynamic memory allocation is false?
a. An object of class unique_ptr maintains a pointer to dynamically allocated memory.
b. When a unique_ptr object destructor is called (for example, when a unique_ptr object goes out of scope), it performs a destroy operation on its pointer data member.
