Answer: (iii) An object is created

A constructor runs when an object is instantiated with new (or through another constructor). It initializes the new object's state. Constructors have the class name and no return type.

class Student {
    Student() { System.out.println("Created"); }
}
Student s = new Student(); // invokes constructor
