Solution

The correct statement is: "A constructor can be used to set default values and limit instantiation."

Explanation:

  1. A constructor is a special method of a class or structure in object-oriented programming that initializes an object of that type. It is used to set the default values of data members of the class.

  2. C# does not provide a copy constructor like C++. You need to manually define it if you need a copy constructor in your program.

  3. Destructors are not used with structures in C#. They are only used with classes to free up the resources occupied by the object.

  4. A class can only have one destructor. Destructors cannot be overloaded. Therefore, a class cannot have more than one destructor.
