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

c. By default, each inherited constructor has the same access level (public, protected or private) as its corresponding base-class constructor.
d. If the derived class does not explicitly define constructors, the compiler generates a default constructor in the derived classeven if it inherits other constructors from its base class.
