Answer
Exam answer
(c) Constructor overloading.
Explanation
Read the question precisely: it says CONSTRUCTORS, so the answer must be constructor overloading, not method overloading — options (b) and (d) describe the same idea applied to ordinary methods. All the constructors carry the class name and are distinguished only by their parameter lists. A copy constructor is a special single constructor that copies another object, which is not what is described here.
In words
Constructor overloading.
