Right choice is (a) Default constructor will not be created by the compiler implicitly

To explain I would say: When the programmer doesn’t specify any default constructor and only defines some parameterized constructor. The compiler doesn’t provide any default constructor implicitly. This is because it is assumed that the programmer will create the objects only with constructors.
