Detailed Explanation
Answer: (D) More than one of the above
If appropriate constructors are not declared by the programmer, the C++ compiler can implicitly provide certain constructors.
A default constructor may be implicitly declared when the class does not have a user-declared constructor. A copy constructor can also be implicitly declared when it has not been declared by the programmer, subject to the C++ language rules.
A parameterized constructor is not automatically created simply because it is not defined. Therefore, the correct answer for this question is More than one of the above.
